Server Crashes On Startup

[SjsolisZXA]

Hello, although Kits has not have had any releases for the Sponge 6 or 7 API versions, I figured I'd submit this bug I've had with Sponge 7, incase you were interested in updating Kits. The server simply crashes on startup when I have Kits installed. Overall, great plugin and I hope I get to use it again.

Sponge Forge Version: spongeforge-1.11.2-2282-7.0.0-BETA-2302
Sponge API Version: 7.0.0-20170502.073700-3
Kits Version: 1.7.4
