When I first tried to buy/sell claimblocks with my full mod list, nothing happens. Claimblocks don't increase, and /balance from gunpowder-currency is unchanged.

The issue occurs with multiple buy/sell prices for claim blocks (1, 20, 25 etc)

When disabling all mods except for gunpowder (and currency module), flan, fabric-api and kotlin, the problem gets worse: the server just crashes.

• Minecraft: 1.18.1
• Fabric(API): 0.45.0+1.18
• Fabric loader: 0.12.12
• Flan: 1.18-1.6.6 (also fyi your version format is the reverse of the conventional format other mods use, which list the minecraft version last. just a bit confusing)
• gunpowder-base-1.1.1.1+1.18.1
• gunpowder-currency-1.0.8+gunpowder.1.1.1.1.mc.1.18.1

error in server console: https://pastebin.com/CuDp47d5

I'm having troubles building the JAR with gradle, is there any way you could publish this as a release, or upload and link a working jar somewhere?

Gradle says the build is successful, but the JAR file is only 1kb and does nothing.
