Instant restart may turn static fire invisible
Restarting Tilarus' SynTek Hospital speedrun over and over (less die pls) on someone else's host, most of the time the static fire at the entrance was invisible (not only for me) until first extinguisher hit but would still ignite marines normally. May be related to marine/camera position before restart. Once saw this happen in BioGen's Invisible Threat as well. Never happen before instant restart was introduced, so I assume it's that. Never managed to reproduce in singleplayer, not sure whether the problem is still actual.
Happened in Tarnor's Abandoned Maintenance Tunnels. d_tarnor-amt_fire-invis_t12000plus.zip Restarted at tick 12000, gates to fire open at t13800; jumping the demo past the restart may cause the fire to display properly.
