Hello YSIAD_RIP,
MOSFETs usually stay fine, since those resistors are "guard" resistors protecting the chip.
I think you need to replace the motors and the resistors.
Instead of the resistors I'd recommend to use Resettable Fuses, 200 mA per motor. Like this one https://uk.farnell.com/bourns/mf-nsmf020-2/multifuse-smd-0-2a/dp/1206716
