Game Version: 0.5.42
1) I've been encountering bugbears related to linked dungeons. Today I came across one that appears to be affecting doors. Any doors, double or secret, that are opened, and left open, on Map 1 with the same names (i.e. doubledoor1, secretdoor1) on Map 2 are open when I transition to Map 2.
2) Already posted this in two other peoples threads, but it's probably best to post it here once more. Lore Areas placed within 1 square or adjacent to an entrance from a another linked dungeon (entrance to Map 2 from Map 1) wont trigger.
