Broke my build plate glass - might be more damage in the extruder

It seems after breaking my glass due to not checking the nozzel for hardened plastic from a previous print, when homing z it just kept going because the endstop never triggered.

Something else after this is that my nozzle now moves forward a small amount when printing. Has anyone experienced this before with the itty bitty dual extruder? If so should I be reprinting the whole thing or do you have an idea of which part is the most likely culprit that needs reprinting?

Thank you in advance,
