As a consequence, the special spikeball has no need to be special anymore. * Made emerald gaining function be based on special stage number rather than gained emeralds! * Consistency with...

(Rings are 300, same as usual, while Spheres are now 1706 replacing NiGHTS Wings.) SPECIAL STAGES IN GENERAL: * useNightsSS is now dead.

MONSTER COMMIT. OLD SPECIAL STAGES: * Spheres in old special stages instead of rings! * Individual timers in old special stages instead of a global one! * Old special stages use a variant of the NiGHTS HUD now! * Special stage damage in old special stages loses 5 seconds of time instead of 10 rings/spheres! * All damage gained through old special stages is converted to special stage damage! As a consequence, the special spikeball has no need to be special anymore. * Made emerald gaining function be based on special stage number rather than gained emeralds! * Consistency with... NiGHTS SPECIAL STAGES: * Spheres now flash in bonus time. https://cdn.discordapp.com/attachments/400761370800422922/452590553100713984/srb20032.gif * Sphere and ring mapthingnums are now less fucked up in 'em. (Rings are 300, same as usual, while Spheres are now 1706 replacing NiGHTS Wings.) SPECIAL STAGES IN GENERAL: * useNightsSS is now dead. Each individual special stage is now assessed for NiGHTS-mode behaviour based on maptol & TOL_NIGHTS. * CRAWLA HONCHO\n CAN NOW BE\n SUPER CRAWLA HONCHO end tally modification now also includes a mini-tutorial on turning super. https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif * SONIC GOT A CHAOS EMERALD? https://cdn.discordapp.com/attachments/400761370800422922/452623869497573386/srb20034.gif NiGHTS NON-SPECIAL STAGES: * Colour Chips and Star Chips! Replaces Spheres and Rings of NiGHTS Special Stages. * Colour Chips turn yellow in bonus time. * Ideya! * Its own "drowning" music! * All of the object types for Dream Hill. * GIF: https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif RANDOM BS: * Turn super with the spin button instead of the jump button! * Followmobj now correctly set with P_SetTarget instead of pointer assignment. * Emerald hunt uses new sprites! * Made unlock noise different from emblem gain noise! (It's the CRAWLA HONCHO CAN NOW TURN yadda yadda sound from S3K now.)

// The line just after that comment is an awful, horrible, terrible, TERRIBLE hack.
//
// Basically, the fix I did in order to fix the download freezes happens
// to cause situations in which a player number does not match
// the node number associated to that player.
// That is totally normal, there is absolutely *nothing* wrong with that.
// Really. Player 7 being tied to node 29, for instance, is totally fine.
//
// HOWEVER. A few (broken) parts of the netcode do the TERRIBLE mistake
// of mixing up the concepts of node and player, resulting in
// incorrect handling of cases where a player is tied to a node that has
// a different number (which is a totally normal case, or at least should be).
// This incorrect handling can go as far as literally
// anyone from joining your server at all, forever.
//
// Given those two facts, there are two options available
// in order to let this download freeze fix be:
// 1) Fix the broken parts that assume a node is a player or similar bullshit.
// 2) Change the part this comment is located at, so that any player who joins
// is given the same number as their associated node.
//
// No need to say, 1) is by far the obvious best, whereas 2) is a terrible hack.
// Unfortunately, after trying 1), I most likely didn't manage to find all
// of those broken parts, and thus 2) has become the only safe option that remains.
//
// So I did this hack.
//
// If it isn't clear enough, in order to get rid of this ugly hack,
// you will have to fix all parts of the netcode that
// make a confusion between nodes and players.
//
// And if it STILL isn't clear enough, a node and a player
// is NOT the same thing. Never. NEVER. *NEVER*.
//
// And if someday you make the terrible mistake of
// daring to have the unforgivable idea to try thinking
// that a node might possibly be the same as a player,
// or that a player should have the same number as its node,
// be sure that I will somehow know about it and
// hunt you down tirelessly and make you regret it,
// even if you live on the other side of the world.
