Pokemon Go players on Reddit identified a serious new bug that could potentially ruin an entire raid group’s experience. The new bug would prevent the catch screen from appearing after beating a raid, meaning that players couldn’t attempt to catch Pokemon like Ho-Oh. The bug had plagued players for several days, but it was difficult to determine what was causing it. On Saturday, players discovered the “trigger” for the bug. Apparently, if a player dropped out of a raid group mid-raid, it would cause all other players in the group to not see the raid boss catch screen. Luckily, Pokemon Go identified the problem on Saturday night and quickly issued a fix.
