Is there a way to make this mod playable with cats and rats? Do I have to load it after cats and rats or before? I had both loaded before but I had so many errors that I just decided to do a new install of everything.
As far as I can tell, this is perfectly playable with C&R-- at least, it is with the http://www.gamesas.com/bgsforums/index.php?showtopic=764521&pid=11207941 (which was really to create compatibility with the guard behaviour that had been updated by several mods, including MMM itself, rather than to deal with any issues with H[C]... since there weren't any issues with H[C]).
I have zCats&Rats.esp loading after Harvest [Containers] Combo.esp, and haven't noticed any major problems; there are some containers that don't animate, and maybe that's because the animation was taken away when C&R replaced the crate with a non-animated one to spawn the rats, but maybe it was because those types of crates just have no animation even in standalone H[C].
Can't say I've been disturbed by it, and there's cats and rats all over, so it's good enough for me.
