One of my players is periodically getting kicked from our server, the only error message I see in the logs is this, any idea what may be causing this? I have no issues farming / carrying aubergines

Unable to get seed from crop mysticmods.mysticalworld.blocks.AubergineCropBlock$$Lambda$29869/534605745 cannot be cast to net.minecraft.item.Item

Can you specify which version of Mystical World and which version of Minecraft?

It looks like someone is trying to convert a Supplier into an Item which... shouldn't be happening.
