Fixed Sniper Rifle not firing bullets due to yesterday’s firing fixes
Fixed some pure server exploits related to the sound system
Temporarily disabled the func_nobuild entity so that testing / QC can be done for various building placement exploits masked by mapping workarounds
Airborne status (commonly used for the Market Gardener) is now preserved for a guaranteed 60ms (up from 15ms), to further reduce the impact of networking conditions
Unducking in the air is now prevented in cases where it would cause you to become grounded
Note that this expands an already present grounding check by two units, to include the two unit threshold from the ground, rather than merely checking the ground level directly
This fixes an issue where on 64 tick / substepped movement, crouch tapping could cause the player to become grounded due to slight differences in jump height steps per tick
This also fixes a potential issue while rocket jumping and momentarily letting go of crouch causing you to become grounded on a ramp
