A discovery I made about S4S creator names and making poses

I recently helped two people who were trying to make pose packs, but the sim would just idle in game. Their Blender files looked fine, and after I remade the packages from scratch and copied and pasted their poses into a blank clip and they worked in game. I couln't figure out why mine worked. Well I think I finally solved the mystery: I noticed that they both had a period in their S4S creator names. I tried putting a . after mine and made a couple of test pose packs, and they didn't work either! So if anyone else is having this problem, try taking any odd characters out of your name, then remake your package from scratch and paste your pose into a newly exported blank clip and it should work.

*Edit: According to Feyona this is an old issue that that I had never heard of, that has resurfaced with a patch. Well I felt smart for a while at least, lol!
