Hello everyone!
I use Blender to make graphgan patterns, which means I have a set number of faces [Edit: up to 14,400]. Each color is its own object, so I frequently separate faces and rejoin them to another object right away. I’m now at the point where I only do this a few faces at a time. There were no problems when I created the file several days ago (and in similar files over the past couple of years), but starting yesterday (4/25/17) it would crash after a few rounds of separate-join. I tried restarting the computer; closing out all other programs; searching online for other people with a similar problem; removing excess vertices (there were almost none); removing all other scenes; deleting extraneous objects; turning off the computer for several hours; and then dusting it out. It now crashes after the first separate-join combo.
I’m sure there must be a simple fix, I believe I had this same problem a long time ago, I simply don’t remember how I fixed/got around it.
Thank you!
EDIT: So I replied below with my eventual solution, if there are any possible explanations for the whole event, I’d be happy to hear about them.
