warping with petg

Randomly in the last few days I have been getting warping with petg on my minion, I’m using standard configs with Prusa slicer and the room doesn’t have any cold air coming through. No idea why this is now happening

It’s polymaker petg and I’m using a 4028 fan at 20% which has always worked fine

Is your house now colder? I noticed now that it is winter I am getting intermittent under extrusion unless I bump up my normal temp by 5⁰

Yeah It seems pla works fine, petg or abs doesn’t which makes me think the steel sheet is the issue The other side is bare so I might just put painters tape over it Just to confirm water isn’t really good with the textured sheet right?
