Crashes when working with data tables

Hi, I have constant crashes when I try to work with my data tables, inside but it also crash sometimes when I try to do a “get table rows” for example. I wondered if it would not be too full of information. Crashes appear after a few moments when I try to modify them (adding stuff inside) I’ve made these data tables to put all of my skins for each body part (Hair, top, bottom…) with diferents direction (8)
My memory is correct (around 50 - 60%)

Also I am thinking if 180 000+ files could cause some troubles ?
There are 2D sprites / flipbooks, It’s pretty well optimized (big sprite sheet with Json files)
sqsd

Here’s the structure that my data tables are using

If nothing work I can delete a lot of files, but I’m not sure it will work after that and then losing everything.

Excuse me, but is it possible to ask a leading question in the form of a meme? :grin:

I just learned something and it made me laugh
Apparently we can’t unload soft references in blueprint for now. So this can help but can’t solve the problem
I tried to break some references that use those data tables and now my engine crash only after 10 or 15 minutes instead of 1.

Thanks for your answer
