For the first time in a couple weekends worth of work, BKCommonLib is ready for some first testing. The problem is that Spigot is trying to convert the plugin to use legacy material logic, and I want it to NOT do that. Its choking on the plugin currently: What do I put in the plugin.yml to disable this? I already tried adding this to my plugin.yml to no effect: Code (Text): api-version: 1.13 Come to think of it, it may also be related to at-runtime code generation. I might have to hack some stuff in to stop Spigot from interfering.
