Hi there,
I'm having the issue that Caterpie and Weedle sometimes evolve at Lvl 7 (as they should) and sometimes I don't get the prompt to initiate the evolution at all.
I found a thread from last year: https://pokemonrevolution.net/forum/topic/160587-metapod-and-kakuna-not-evolving/?do=findComment&comment=893260
Is this still a known bug? Since I caught both Caterpie and Weedle at Lvl6, they shouldn't be "too happy" yet...
Or maybe it's a new bug? So far, it happened on the silver server and also showed up when I switched to another pokemon to end the battle.
EDIT: Using another pokemon for battle doesn't seem to be the reason. I just fought a battle with Caterpie alone, levelled up to 7 and it didn't evolve.
One other thing that could be: maybe Viridian Forest is the problem? I had evolutions on Routes 1&2, but none in Viridian Forest so far...
