So just 5 mins ago limits on cobble and ice were set at 1000 i see why this was done because of lag caused due to how many lava/water blocks were placed what i suggest is maybe try and limit number of lava source blocks u are able to place on your island? if this is able to be done this wouldn't waste the countless hours people have spent on levels and would stop lag and i say this as the 1000 limit has hurt me my team and @GeorgiaMC 's team, thread is bad ik
