  I am also running the latest versions of other mods that are part of my problem.

Did you check on the Wiki? or ask on Discord?

• I checked the MineColonies Wiki and made sure my issue is not covered there. Or I was sent from discord to open an issue here.

Current Behavior

I have tried this with a clean instance, just minecolonies and whatever dependencies curseforge auto installed. The issue begins when a request for concrete is placed, either by postbox or builder. A courier will take the necessary materials to mixer, he starts making powder and he turns the powder into concrete. There are two things that might happen next. He either places a few blocks in the rack or he keeps it all on him. The courier comes back, finds no concrete (even the few blocks) and creates a new task in the warehouse for more materials for concrete. Even if at some point he places enough concrete to complete the order, the courier refuses to pick them up and keeps bringing more material which is turned into powder and then concrete. When you manually request a pickup, the courier will get the concrete and put it in the warehouse, instead of completing the original request. The mixer will continue making concrete until you cancel the request or use the reset request command (if there is enough concrete in the warehouse, otherwise the loop will begin again). Something similar happens when requesting just powder. He makes the powder but starts converting it into concrete. The courier keeps delivering materials for powder and creates another loop. This issue has been tested by me and another person on discord, on brand new minecolonies instances with no other mods, with the same exact results.

Expected Behavior

Request concrete, couriers provides materials, mixer makes powder and converts to concrete, courier picks up concrete and delivers the original request (player or builder).

Reproduction Steps

1. Add a stack of sand, gravel and dye to warehouse
2. Request concrete from postbox
3. Watch as the mixer creates concrete for ever
