Bringing back this thread:
TF2 patch notes.
So many bug fixes as of late
Fixed a client crash related to the material system
Fixed a client crash related to ragdolls
Fixed a client crash related to demo playback and skipping ticks
Fixed sentries not being able to hit players who are ducking while airborne. This was most noticeable when used in conjunction with the B.A.S.E. Jumper.
