Sorry for my English. I came from Germany.
When the Potion Brewer make the last recipe for the "lingering_potion direct_damage II" then the Server Crash with a "ticking Tile" Error. The Brewer NOT USE the Water in his Slot. (Is Infinty)
To Reproduce the Error go following steps:

Power the Brewer, feed with Blaze Powder, Glassbottles in the Slot and 1 Bucket of Water.
Add Incredence in following Order in the top Slot:

1. Netherwart
2. glistering_melon_slice
3. fermented_spider_eye
4. gunpowder
5. Glowstone Powder
6. dragon_breath

The first 5 Steps works perfected. When the last Step ENDS, then the Server Crash. (It crash EVER when make, HOPPER below the Brewer remove the water-bottle on the Brewer, NOT the Potion) Help for this is only kill the issue with FORGE CONFIG! You must the Server run ONCE with the "removeErroringTileEntities = true" command in the "forge.cfg" File.
This command remove the entire Inventory of the Brewer, but the Brewer is still working.
I have NOT tested with other Potions.
