Paper/Spigot-Server-Patches/0042-Add-FallingBlock-source-location-API.patch
Zach Brown 233814297b Remove the spigot TileEntity/Entity capping feature 
It appears to cause visual glitching issues with certain TNT entities
fired from cannons. TileEntity tick capping has already been removed
for some time, Entity tick capping removal is new to this patch.
