Shadow Guild at White Cap
There is a secret room in Shadow Guild (in White Cap), where 4 coded doors with teleports behind.
When i tried to type the answer for the south coded door (time), when i typed "E", the dialog was reset and the game showed me "Incorrect" in the log, so i was unable to enter correct answer. At 1st i thought this is a bug, but then i released that i have "E" key binded to "Trigger" action (instead default spacebar), so it was logical that by doing so i manually skipped/dropped the input dialog. So there is probably a question about scripting such hot key exceptions for input dialogues.
If you open any coded door and then save and reload, the door would become closed again (and require password). Such behavior was in MM6, but i cant say if this is a correct behavior or bug (more like a bug to me).
When you teleported from the braziers room to the room with spawned genie and (now active) portal to the secret room with coded doors, there is no a special wall texture indicating that there is teleport trigger here.
I suppose genie is spawned every time you teleport from the braziers room, so there is a question if this should be so.
