Do have any permissions or OP? Or any plugins that could interfere with inventory switching? I tested it on the testserver and couldn't reproduce.

[Hans Kurel]

If you can, please post you plugin list here or send it to me on SpigotMC PM. Maybe I can find a plugin that's causing it.

[Former user]

This kicks cause this.

[Hans Kurel]

I suspect it's Multiverse-Core that's causing this. Try removing it and report back.

[Former user]

The a Multiverse-Core important plugin and not removable. Need to PlotSquared.

[Hans Kurel]

But can you make a copy of your server and test it without affecting the real server? If you could verify that Multiverse is the cause, I could investigate further.

[Former user]

I don't know how to exactly reproduce this bug.

[Former user]

A server player was able to reproduce.

Generate world speed fly + F3 + C = crash client when generated world cause survival inventory lost.

[Former user]

The Restricted Creative v1 inventory system always worked perfectly. I don't know why this updated inventory system. :(

[Former user]

A server player method doesn't work for me.

I can't test it without Multiverse this bug.

This method always works for a server player. I don't know why.

[Hans Kurel]

It seems that RC has trouble saving player's inventory in such cases, but I can't really fix it if I can't reproduce the problem. You can revert back to v1-like inventory system by setting general.saving.inventories.enabled to false in the config.

[Hans Kurel]

Beware that turning this off will currently not restore the survival inventories of those who logged out in creative mode. I'll add support for it in the next version.

[Hans Kurel]

It's safe to use in the next version.
