Thanks for the answer. I would upvote but I don't have the necessary rep yet.

R.. GitHub STOP HELPING ICE
<p>I've noticed there have been some strange patterns occurring in my prints lately, sort of like warping. I've attached a picture of a Benchy below and an image of a project I'm working on. But as you'll see on the Benchy, the front is messed up. Never had this issue before, it's only started occurring recently. Any ideas as to what it looks like?</p>

Looks like insufficient cooling. If it only just started, your part cooling fan might be clogged with dust and debris, or have a failing bearing making it spin slow and give low flow, or might have broken fins, etc.

It's also possible that a difference in ambient air has made the difference. Especially if you're printing PLA on a hot bed, it's hard to get low-to-the-bed overhangs like the Benchy bow sufficiently cooled that they won't deform like this, and having the ambient temperature a few degrees higher can make the difference in not being able to.

If the latter is your problem, lowering the bed temperature (and finding alternatives to heat to get your part to stick) is probably your best option. Or, get better fans.
