-- Block entity being ticked --
Name: botania:pool // vazkii.botania.common.block.tile.mana.TilePool
Block type: ID #9 (tile.water // net.minecraft.block.BlockStaticLiquid // minecraft:water)
Block data value: 0 / 0x0 / 0b0000
Block location: World: (127,52,127)
You'll need to use a world edit program to remove the pool.
