So a Snorlax just spawned and i went to battle it, It used rest then nothing happened. The battle menu would not pop up i tired everything to get something to happen. I was not lagging not even the slightest bit it just wouldn't work. A mod suggested disconnecting and coming back but the Snorlax was already despawned so that clearly wouldn't of worked. This happened to several other people and none of them were very pleased. Someone else also said the battle froze for them after Snorlax used rest too. Might be a coincidence or maybe it has something to do when he uses rest. But ether way a Snorlax spawned and me and several other people didn't even get a chance to throw one ball at it. Totally unfair and quite discouraging to keep playing this game if these things are gonna happen.
Yes, this glitch has happened to other people too and they have also reported it. I think the staff is aware of it by now and will be fixed soon.
