I am on phar build 251. I simply cannot do anything in my inventory. Trying to build planks results in this error on the server and then I they roll back to tree blocks. I can move but sometimes it resets me back to where I was. error [Server thread/CRITICAL]: ErrorException: "Undefined offset: 0" (EXCEPTION) in "src/pocketmine/Player" at line 3032
Seems that switching to the mobile GUI fixes that issue. Really sucks because the mobile is a bit cumbersome on a laptop. Now I am getting skipped around a lot. The server says I moved wrong... Looking into that one now.
Animals and Mobs are not in PMMP yet. Use https://poggit.pmmp.io/ci/RevivalPMMP/PureEntitiesX/PureEntitiesX, it's the best plugin for it so far
These are windows 10 inventory bugs and they will be fixed in future versions. The pmmp team is waiting on Mojang to release there inventory rewrite.
I have the work around for that one and can deal with it. I fixed the jumping around while moving by switching off the cheat for moving. And now I am working on trying to get mobs to show up. I downloaded the PureEntitiesX from above but nothing showed up because the server stated that it was incompatible with the API version. trying to resolve that one now.
Moved to Nukkit. The dev worked the mob plugin quickly and got it working. There are things missing from Nukkit like not movement protection so I am constantly being pegged for illegal movement lol but hey mobs are running. But what I like most about Nukkit is it is Java so I can mess with it big time. I'll be checking in here often because both seem to move quickly.
I actually just moved from Nukkit, back to PocketMine. I only came back because PocketMine has more plugins to use, but, I'm trying to figure out the whole "syncing pack with server," and "building terrain." I'll get past it, it just takes time.
I actually have both loaded up right now. Pocketmine seems better but the lack of mobs makes the kiddos unhappy so I tried Nukkit and the dev for the mobs AI plugging worked on it quickly to resolve the issue and got mobs up and running. I'll be playing with both until a clear cut winner emerges. As the issue you mentioned I have not had that issue. All of the clients connect just fine.
I've researched into that issue. All of them seem to say it's either the server's fault or it's a client issue. I'm not sure where to go from there, since none of them seem to have any actual solution to the issue.
