Instashield crash fix
Crash in question: https://files.catbox.moe/afj937.mp4
This branch fixes instashields not being removed if the player instashielded, then disconnected, which caused a crash. This was done by removing an extra K_MatchGenericExtraFlags
that was being called before validation was being done, and that would already be called anyways due to the P_MobjThinker
switch fallthrough in MT_INSTASHIELDB
.
No build because this is a trivial fix.
