Merge branch 'fof-flag-change-hotfix' into 'next'

Fof flag change hotfix

This fixes rendering issues caused by changing FOF flags mid-level via Lua or linedef type 445. Everything else that toggles FF_EXISTS already had this fix it turns out.

Not sure if this is safe for master too, could someone check that for me?
