commit a41911f8907731c098de71ca3e14261ac432ec8c
Author: Rachael Alexanderson <madame-rachelle@users.noreply.github.com>
Date:   Fri Feb 9 11:59:16 2024 -0500

    Revert "SpectatorCamera can now follow the 'tracer' actor. Also added a 'lagdistance' property for lazy follow."

    This reverts commit 7fbb4cd06c.

commit 19398edd065b7b483b8c7be42cb16026695e241a
Author: Rachael Alexanderson <madame-rachelle@users.noreply.github.com>
Date:   Fri Feb 9 11:59:05 2024 -0500

    Revert "Minor addition toe SpectatorCamera. Added three chase modes to lazy follow. 0: Catch up until tracer is centered again. 1: Same but don't move if tracer isn't moving (camera moving when character is not is jarring). 2: Stop chasing if tracer is closer than lagdistance. Game modes benefit from a 'center camera' button but that doesn't have to be hard-baked into the engine."

    This reverts commit c3ca564cfc.
