TYVM John and others for the hard work. Really appreciate it.
I have been having loads of fun discovering some stuff (like the flag trick on my own, before reading about it here, and other things).
I just think that some people either are playing in JP (kudos if you are, I have given up a long time ago playing the originals in native language), or have trouble using the search on this forum. I mean, most answers are already there... And most things you can 'fork around and find out', by using save slots.
E.g., can't make NPCs pregnant before recruiting them, bosses don't respawn, but basically everything else that isn't unique does (if you don't block the spawn), you can place stuff in the raft and move the raft, so they will float MC style...
