As you know, 1.14 presented some unexpected challenges, especially when it came to plugin compatibility and server stability. After some efforts, I've assembled something that I believe should be stable, and it's ready for widespread testing!
For this, I'm bringing back our 1.13 test world, Tasmantis. You can access it from the lobby using the latest Minecraft version, 1.14.3. All the features that you're used to are in. Due to incompatibilities between game versions, you'll access that world at spawn, with no inventory.
If everything goes well, the full network will be updated to 1.14 Saturday the 13 of July, two weeks from now. Your global inventory will then carry over to Tasmantis, allowing you to retreive any materials you'd like to the main servers. A week after that link-up happens, Tasmantis will go back offline.
Important: if you decide to play on Tasmantis, either to try it or gather supplies, your personal inventory on that one server will be overwritten at the moment that the rest of the network is updated. As such, anything that you'd like to keep from there should be placed in chests. Enderchests should be avoided as they'll be overwritten too.
