Fix | There have been quite a few problems with running Jumppads on 1.13 servers. Mainly it was the issue with leaving behind entities when landing and particles sticking. After a lot of testing, I found that 1.13 servers will actually convert the entity into an invisible "block" without truly being a block when landing. I've implemented some extra logic that'll prevent the conversion. Hopefully, this should make the plugin run on 1.13 without issues.
Thanks to @mibby for providing the error circumstances!
If 1.13 still causes errors please shoot me a PM and I'll take a look at it!
