I am having the sam issus and noticed it in the nether where the lava is generated as red water.
I am using the ubuntu version of the Server. Our server has not had the most recent update 1.14.60.5 it was 1.14.60.2 . We are not using any addons.
This is the Bedrock Worlds Server File before any new chunks are generated. So my Backup before the Update: https://cloud.wieser.myhome-server.de/s/rMe4ZRGKrbr77Fj
I upgrade the Server by just replacing the Old bedrock_server file with the new one of 1.16.0.2
To mention i had problems with disappearing chests mentioned here https://cloud.wieser.myhome-server.de/s/rMe4ZRGKrbr77Fj
If you need all server files or the world with infected blocks let me know.
The Picture says Invalid IP-Address.
The client tried it again without entering the Ip address and it worked. It was only when it happened during the day when on my side nothing changed with the DNS settings.
Thanks for the support
Ok i will let him try it again but what is strange for that when my IP address didnt change during the day he suddendly couldnt join any more.
Yes it is still happening. You can still join my server and see it. Maybe contact me then i also can send you the files @IconicEcko
For me this solved the issue
