Thanks for the advice :smile:
The raised strip ran from the front of the bed toward the back about 100mm. going between two separate parts (one of which is below).
I've printed since I had the issue without problems. Which is a good thing I guess. I would like to understand the problem though.

It could be many things - most related to leveling. If leveling leaves too big a gap then the PLA doesn't stick well and kind of falls down onto the bed - you want it squished. It leveling leaves too small a gap and you have a UM2 then the extruder will skip because it can't get all that PLA in such a small gap but the skipping will cause underextrusion. Picture would help.
