I've noticed that Larian has changed how a couple of the pressure-plate traps work. For example, in the blacksmith's basement, there's a pressure plate which sets the fireballs to going, and a lever to turn it off. If you weigh down a plate with the oil barrel, and turn the traps off, walking on the pressure plate no longer does anything - it doesn't start the traps up again. Excellent, thank you!
There should be additional triggers for vendor restocking
my suggestion:
- if at some point in development you tried to implement the day/night cycle you should have an internal clock, just make a timer and respawn vendor inventories after "X" days.
A couple patches ago, if you waited a couple hours with the game running, vendor selection would refresh. Even if that's still in, that's not ideal for obvious reasons.
