So me and my friend are fighting the ender dragon with the modpack, all the mods 3. When all of a sudden it crashed saying "tried to read NBT tag that was too big; tried allocate" which after searching through the forums and mod pages I found meant that it was using too much memory, but what I couldn't understand was how it surpassed the amount of memory even though nothing was happening. as it turns out gravestone (the mod that gives you a grave when you die to get your stuff back) uses a ton of file space, which would explain why the size was unable to be read because we were dying a lot. so my question is how do you either delete the mod or remove the graves.
thank you
