fortog route 1 crash

so, i try to catch a fortog in the pond next to the fishermans house, and after i give it a nickname the game crashes, does anyone else experience this issue?

Yes, this is a known bug and is already in the FAQ topic. To avoid it, either register the rod to f5 or make sure you have 6 Pokemon in your party while fishing.

Thx m8, this was really helpfull, meanwhile i avoided the bug by catching my fortog on route 3
