Kicked after using the /claim command gives me RPC Error in RPC_WantsMount

also this is in console

Figured out using the claim command breaks it. also i used the first /spawn command boat and it worked for roughly 20 secs before turning invisble and kicking me out of it, now everything i spawn is invisble its there because my character hits a collision while running into it i just cant see it. Tried reloading plugin and reinstalling plugin the mod is now broken on my end.

Mind getting the full error from your server logs?
