Well there 2 issue important in shift2_1 (shift2_2 didnt see anymore)
- After take gun in security camera (*246), go back to elevator but elevator door didnt open (outside open but inside didnt open *249 and *250). Not like v1d before.
- Elevator door (2 buttons *240 and 1 button *104) still unlock (can press) without "go Elevator Access room and press *160" => Forgot add link with elevatorms and mp1 (there is multi_manager or func_button) or multisource problem (I'm not sure for it) but need go Elevator Access room 1st then go elevator to allow use button elevator.
(Suggest other) scientist2 at start game will be stuck at door (can't open again) when door close porte3 (*206, *207, *208, *209) and npc move inside while door closing without knowing it => Keep this door + glass door (all 4 model) stay open
(Optional) barn wave still disappear in train (*81) after fix and play v1e so I just ignore this as well. It's up to you.
