Someone please help with crashing Pixelmon server

Hello all, I’m hoping someone will be able to tell me what’s wrong on my server and how I may be able to fix it. Everything that I’m running is listed below. I started realizing that upon one of my restarts that blocks were randomly replaced with others and in random places. Whenever I go into a building with interior (PC’s, tables, random items) the game client crashes each time for myself and any other player on the server.
Here is the crash report:

This looks like a Pixelmon issue as sponge isn’t loaded in the crashlog.

Looks like as if you are using a Bukkit to Sponge port, which limits our ability to help.
Porting plugins from Bukkit to Sponge is a very experimental process carried out by developers.

Any idea what the issue “might” be ?

Looking more closely, since I just used Chrome finder at first…
I noticed that this error report is specifically for the client, and not any link to the server.
Is the server crashing too? If so please post the server crash report as well.
I have encountered many client crashes related to Ticking entity, seems quite common.

The server does not crash, only every players client

It ‘crashing every time they join’ seems quite weird, did this just happen recently?
Or has this been happening since you created the Pixelmon server?
Have you tried updating to the latest sponge and forge version?

Remember there is in fact experimental builds of Sponge, those are counted as the ‘latest’.

Doesn’t crash when they join. Only when entering any of our buildings with interior items and blocks that we’ve been working on. We just updated a few days ago to newest versions and that’s when the problems started happening

That is some valuable information you just provided, something that should be in the thread.
So it started happening since you updated? Have you tried the interior blocks on the old version?
The mods may not even be updated to the latest API, which may be why they work best on the old version.

Thank you, we will try that now

That did nothing unfortunately.
What does this mean exactly:
java.lang.IllegalArgumentException: Cannot get property PropertyDirection{name=facing, clazz=class net.minecraft.util.EnumFacing, values=[north, south, west, east]} as it does not exist in BlockStateContainer{block=minecraft:grass, properties=[snowy]}

It means that the Direction value isn’t set for the BlockStateContainer being processed.
Normally mods or more importantly forge would have a safe guard against these kinds of problems…

UPDATE: for anyone that can help:

What you haven’t told us is what mods/plugins are running on the server. I’ve crashed my client because I’d accidently processed a block on the server on an async thread before (and I bet that’s possibly happening), if we know what you’re running there, it might become clearer what’s going on.

If you have any custom plugins, make sure that they do all their block processing on the main thread.
