Bug1: I'm not sure if this helps, but when I jumped in the well in lakeview as a heavily pregnant Leah, I got an error about failure to load: $Leahnewfacespreg3_stage2_3.png. This file does not exist. So I looked into the code on Notepad++ and on line 111 of Common Events, I found that this is the only place that this file name is referenced. I'm not sure what file it's supposed to be grabbing, but this seems to be an old bug that was never fixed.
Bug 2: As of the current build, all of the secret 'lairs' that bring you to the hooded king that kicks you out if you come to close, all link to the Brood Sanctuary south of Lakeview. Two issues with this: One, if you haven't picked up the golden egg quest, you are now soft-locked. Two, because you entered the Brood Sanctuary from a different entrance, none of the traps do anything as the 'Egg Bar' isn't currently active.
Bug 3: You can call your boat on the passage between Royal City and Demon City, and if you sail over to the salt pile(?) on the Demon Continent and hop out of the boat, you are now soft-locked.
