I can confirm, my server has been unable to update to the latest version. I checked the web page, and it still has the previous version of BDS for the Linux download link.
This was still happening to me as of 1.15.2, but it looks like it's not happening anymore in the 1.16 snapshots
Bump.
I think the lag spikes i was having may have caused the game to skip over those chickens from flapping :\
I trust you're trying this in 13w04a?
No, I just had faithful on my 1.4.6 client, then i used magic launcher to go to 13w04a to more easily switch back.
Probably should take out the red flash when hit, but otherwise works as intended.
Notice the flowing water, the chickens were also there for a long time. And there are a lot of chickens there to add on to that...
I have noticed this issue too. The work around I did was to set the IPv6 port to 19132, then set the IPv4 port to 19133, then set up port forwarding for IPv4 to forward the external port of 19132 to the internal port of 19133. That way the port is 19132 for both IPv4 and IPv6.
You can take this further by creating a domain or subdomain with both an A record and an AAAA record. (Pointing to both the IPv4 and IPv6 address) Minecraft will connect via IPv6 by default, if it’s not available it will try IPv4.
This way all your players can connect via yourdomain(.)com:19132 whether they have IPv6 or not.
Hope this helps
