so after evolving one of my guys i seem like i cannot exit the invetory screen.. might be a massive issue

Uhoh. I have heard this before too. Checking it out.

Sorry Im struggling to reproduce the error, but thanks so much for reporting it. I got this report from someone else too? So its definitely in real in some cases. I rarely check comment here, theres an f95 zone thread and the patreon, where you can comment for free.
