Currently Ace3 isn't updated for DF—the current version is 9.2.7. This doesn't seem to be causing any issues (yet, at least I don't think so) but I'm wondering if it's fully required to run MBF properly, or if there's an alternative in case it doesn't get updated.

A lot of my mods are still pretty borked from the 10.0 changes so I've been going through and trying to get rid of anything I don't absolutely need. Thank you

Ace3 is required, but most current Ace3 release Release-r1294 (Oct 22, 2022) is included. You do not need it installed as a standalone addon.
