The Preserve I have is the one with the halflings that upgrade to Hobbits. I love this town!!! folder in mods says New Preserve. I believe it’s the one from the mods list here.
I honestly haven’t found any glitches in Abyss that stand out to me, I am in the process of some play testing on several mods, I will keep track of areas for improvements, and probably start a new chain.
The biggest glitch I have found so far to my frustration is the shipyard in Cove Town. It is pictured even when not built, and when it is actually in a place where you can build it, you cannot purchase a ship from it. Also I don’t think VCMI actually has cannons yet. (Though that doesn’t bother me too much)
