MinecartCommandBlock entities not working in Sponge

Sponge Sponge Support
1

I tried placing command block minecarts but they wouldn’t place, and then I tried summoning one and it said it could not do it. So I checked the console and found it flooded with errors.

MinecartCommandBlocks fail to exist in Sponge. Here is an error that resulted from summoning a MinecartCommandBlock:

SpongeForge or SpongeVanilla? Does this happen on the latest build?

This was on SpongeVanilla. I don’t have access to my server right now so I’ll need to make a test server to test the latest build, etc.

I tested it in my test server. The same issue is in the latest version of SpongeVanilla.
I also tested without plugins and I have the same issue.

But here’s something interesting. They work in SpongeForge. Just not in SpongeVanilla.
Then when closing and loading with SpongeVanilla, all the carts disappear with a load of those errors in console.

I can confirm there is an issue with command block minecarts on SpongeVanilla. You can use SpongeForge at least until the issue is fixed

I have fixed the issue

Build 295 and greater should no longer crash with minecart command blocks
