I have a very comprehensive list of such issues coming up, but I kinda failed to keep up with all the updates and changes for now. Good thing is that most of them can be fixed with simple mods, e.g the wrong or missing artillery models or units using wrong animations. Models using non-dynamic colours or coat of arms that belong to different tags, however, require advanced modding that goes beyond text edits, so it would be nice to see them fixed by the devs. Mare Nostrum specifically could absolutely use a comprehensive bug-fixing pass, there are literally broken and missing assets, not to mention the original T2 Italian models that got removed in a hotfix for some reason (at least they should have been kept around for modders to use, the current T2 models don't fit the 30y war fashion at all).
