So, I imagine I will get this question a lot the following days. I'm pretty sure I will get it, so I will answer it here.

Does SuperLuckyBlock support 1.14?
No, not yet. Some changes have been made in 1.14 that will (partially) break this plugin, but this is not the only reason I won't support it. 1.14 didn't even release yet! It's a pre-release version. Also, the spigot build is a development build and is not meant for use on production servers. Once the libraries I use get updated(Remain is one of them), Mojang releases 1.14 and spigot becomes a bit more stable, I will update SuperLuckyBlock with 1.14 support and support this version. Until then NO support will be provided for 1.14. You are free to try it on 1.14, but you have been warned.

I will be able to create new updates and fix some of the known issues starting Wednesday, as I get back home today.
