RandomEventsGame::learn ConcurrentModificationException when resetting lore

[hopperelec]

RandomEventsGame::learn iterates through itemsWithLore.get(seed) but also RandomEventsGame::resetLoreFor >RandomEventsGame::removeLoreFor which removes items from itemsWithLore

I think I'd like to fix this by giving RandomEventsGame::resetLoreFor custom functionality, because lots of code from removeLoreFrom and addLoreTo are redundant when used at the same time and lead to issues like this

Why is handling lore such a pain..?
