Anyone have an issue where the extruder fan sometimes touching the filament on the 1st layer of a brim/raft and messed it up?

I have the same issue! What did you do to fix this?
Do use the Original Fan duct? If so, this is not common. Try to unscrew the fan and reassamble it a bit higher if possible.
If that doesn't work - look at how high the nozzle is threaded into the extruder - it may be too high
