my mod crashes servers

[Titanium Man]

so i am making a mini-empires brick pack, which consists of mini blockheads with weapons, along with small forests and stuff
i gave it to someone early, and for some reason they report that it crashes their server sometimes
the only thing i can think of is that the models are too high-poly
can someone tell me why sometimes those servers crash?

You most likely have Quads in your model (4 Sided Planes) Try to find a tri-angulate  Option in your program to fix the issue

Without more information on the servers, the mod, maybe a console.log, I don't think anyone can be sure.
