comet cave boss encounter/event

im not sure if this is a bug or the event just hasnt been made yet.

but at the end of the comet cave when you split up with your rival i saw a 2 headed grozard ( the evolution) on top of the doorway to the next room. when i entered that room a NPC went towards me and thanked me for taking care of that pokemon.

now if i walk back i stil see the pokemon ontop of the doorway but i cant seem to trigger the battle.


also... i dont know if it is intended but for the love of god, the encounter chanse in that cave is high. if i didnt stock up on repels it would take me over 2 hours. all those grozard battles with their arena trap ability makes it imposible to run.
at least my team is now power leveld

this is already known .... this happen to ppl which lost in the battle against terlard before the new update to fix this bug

you cant fight this terlard anymore ( you just lost some exp or 1 pokemon to catch) but you can move on and have fun with the rest of the story
