So I just read on minecraft.net that there could be a release tomorrow! If so, I will immediately setup a parallel 1.13 server which will be accessible by existing Settlers and above levels for the new, temporary darklands. Then, I we will see over the coming days how we upgrade the rest to 1.13, depending on plugin compatibility. I do not expect major problems, but you never know. Also, I will be on vacation for 2 weeks from Thursday on, so please do not expect too much before August :D.
We waited for the Aquatic way too long, so waiting a bit more till August won’t be a challenge :)
Have a nice vacation!
Have fun with the family, see you in August.
