1. when first starting the server it spits out the following:
   [WARN] [RealisticSeasons] Task Plugin sends temperature warnings to players in creative #62 for RealisticSeasons v10.6.4 generated an exception

2. after trying to run the /winter command it overloaded the memory and caused the server to crash, is my guess. I think it could be a memory leak? but not for sure. here is the error that's thrown

Hello, can you try updating your protocollib to their latest developer build? There should be a small link somewhere on their spigot page
