That new mod you want to add sounds like KaiMonkey’s Traits, which I can confirm works just fine with BEAM and ACE.
as @nightlancer points out, you do have some out-of-date mods in that list; and if you’re missing the ACE armours core then that will definitely cause a crash. Glassworks in my experience does cause errors with ACE although I’m not sure if they’re bad enough to cause crashing; but any mod which requires Mod Repairer (e.g. Elves of Veloren) will probably also cause crashes unless you use the mod repairer with them.
You should definitely try to find a crash report; that will directly point you at where/why the game is crashing and help you* figure out a solution.
*or at least help us help you
As for some other decoration mods you might like to use, I absolutely recommend Home Sweet Home, Lost’Ems, Settlement Decor, and Signery – all four play nicely with ACE and the other mods I use; and offer many little details that really bring the town together. One of them (I forget whether it’s HSH or SD) adds a gardener job, and Signery gives you tons of signs to mark your town with; but if you only pick one of those four mods then I cannot recommend Lost’Ems highly enough! Some of the items it adds fit so well that I constantly forget they come from the mod.
A final note: adding lots of mods makes it much harder for your computer to load the game, so you may want to be cautious about over-loading your computer – especially if many of the mods add similar/duplicate content.
