That was my theory because of the damaged hexagons on your original print. Something was causing the plastic from the previous layer to be too high and the nozzle hit it while travelling.

You could also play with your travel settings. Combing may be undesirable on this type of print.

Maybe curling cam be reduced by drying your filament, but I haven’t tried that. Curling seems to happen when the plastic stays molten for too long, often because it is going down too hot or because the nozzle is coming back around for the next layer before the previous layer has cooled enough.
