Hi, @Oldeseadogge - there's an explanation of how to post links
here. You can also click the little chain-like icon that's shown in the middle of the line above your posting window, & copy/paste the address in there.
Earlier today I was skimming through the list of current TS4 bug reports & saw that the answers/ea bug report forum had a report for the 'no pants' issue, if you want to me-too that one. I don't have a specific link atm, sorry, {edited to add:] but if you don't have a window open to the
mainpage atm, here it is. (Finally bookmarked that page today!)
2nd edit: here's the no-pants at Geekcon bug report!
Like you, I have now had issues with sims, even ones w/L-10 cooking skills, starting fires (especially at the oil-drum stove) any time they try to cook; I thought it was because I have the 'cursed' lot trait in that lot, though before the patch that wasn't an issue. I changed out the lot trait but rotated to another HH before doing any more cooking, & haven't needed to do any cooking since. I'll keep an eye on it and go find a bug-report to me-too if it keeps happening.
