map and position concerned by the glitch :
map :
bm_c1a2c
getpos :
setpos 1616.000000 -899.081116 75.622787;setang 0.031073 -85.045120 0.000000
Details of the problem:
I was going from bm_c1a2b (where we see multiple vortigaunts spawning in offices) to bm_c1a2c through the ventilations (by the ladder above a couch) and i was stuck (too low in the ventilation duct) just after the loading of bm_c1a2c finished. upon reloading, i was even lower than before reloading (like seen in the screenshots) (in half-life 1, this duct was used to allow you to go disable a turret protecting stairs)
nevertheless, great game so far
