@@ -12,15 +12,15 @@ We replaced the `blockEntityTickers` list with a custom list based on fastutil's
 This is WAY FASTER than using `removeAll` with a list of entries to be removed, because we don't need to calculate the identity of each block entity to be removed, and we can jump directly to where the search should begin, giving a performance boost for small removals (because we don't need to loop thru the entire list to find what element should be removed) and a performance boost for big removals (no need to calculate the identity of each block entity).
