Weird holes in print

[GamerDarling]

My recent cookie cutter prints have started to have these weird globby holes in them, and I'm not sure what to tweak to make it better. I've tried a few things(temp, layer height, etc) but it seems odd that it would start having these issues after having printed the file multiple times without issue...and it's frustrating to test because the issue doesn't happen until about 40 minutes into the print. (Currently testing another cutter to see if I get the same issue on a different print) I'm betting this is something basic and common, so I thought I'd post here in addition to googling. Anybody see this before?
