Weird Repeatable Ironing Behavior?  

Weird Repeatable Ironing Behavior?

Sorry if this should be in the MK4 forum wasn't sure which was the best route.

I won't claim to be an expert, I may have messed something up. I'm using a factory assembled Mk4 with the out of the box nozzle, PrusaSlicer 2.9.3, and 99.9% default settings (only modified fill pattern to adaptive cubic, enabled ironing, and bottom layer to octogram spiral, sometimes on .20 quality profile, and sometimes on .20 quality). The model was created in Blender and has printed successfully with ironing on countless times, along with all of my other similar prints, none have ever given me issues with ironing. I'm using a single extruder and multiple manual color changes to make these prints.

...I tweaked ironing settings from defaults one time trying to speed up my prints due to an AI recommendation to use .15 for spacing on passes... I tried it, it got worse, so I switched back to the default .1 spacing and 15%. I also tested enabling automatic infill combination left on the default settings. Suddenly almost all of my prints are having these issues (image attached see the orange ironing layer) even after going back to defaults.Is my nozzle messed up? Did I unknowingly tweak something in a profile? Should I be using quality or speed exclusively with these settings? Do I need to change the top layer from the default monotonic lines? Do I need to clean my nozzle somehow? I know It's been cold and I have to open my enclosure a lot for color changes, but this one was done during the warm part of the day and in an enclosure. I'm at a loss. I keep seeing videos saying to tweak my ironing settings in various ways, but the default settings have always worked for me up until recently. What am I missing? Thanks a ton for any help you guys can give, I need it desperately to complete orders.
