Hi im Having a serious issue with the unityplayer.ddl crashing the game im currently in the easter location and about a 1mins30s to 5mins into the game it crashes to a point of unplayability i understand it might be the amount of players there but i also find it happening in places like vermilion,cerulean and even routes that have a lot of players as well as randomly in places with me alone idk what to do about it error file below error 1.txt

Soooo as the topic would suggest what are the players to do about items such as Black MS or the 72h xp boost or a 24h safari pass? I myself had a 72h xp boost because that was all i could afford atm it had a good 9 hrs left on it that i wanted to make good use of will there at least be a rollback of said items if used already or am i saving to get another?
