FastSuite interferes with Pestle and Mortar from the Hexerei mod

[dimon7147]

After installing FastSuite, Pestle and Mortar from the Hexerei mod stops working. Pestle and Mortar just hangs and does not craft. After uninstalling FastSuite everything works as it should.

Modpack: Enigmatica 9: Expert v1.12.1 FastSuite: 1.19.2 v4.1.1 Forge: v43.2.14

The recipe gets looked up every tick from the tile entity (^ I'd recommend asking the hexerei dev to reconsider this approach) And when it checks if the recipe is present, it's not there (This implementation is probably not suited for multi-threading (I don't know how recipes work though))

You can add the recipe type to the fastsuite.cfg to fix it:

    S:"Single Threaded Recipe Types" <
        hexerei:pestle_and_mortar
     >

Solution here is just to blacklist the type, or have Hexerei ensure their matches() functions are threadsafe w.r.t. eachother - the matching once per tick is wasteful but not the root-cause here, the problem is something that one of the recipes does in matches() (such as pulling a tile entity from the world off-thread, or modifying state).
