TC Optimizer not showing ?

Hello, TCOptimizer is noch showing for my players. They can click it but the UI is not visible.

What exactly are the permissions for ?

They can click on what? Because they only have to open the Tool Cupboard, select the number of hours of protection they want then click on the number and it will take items from their inventory to the Tool Cupboard if needed.

The UI does not even show up.
The mouse shows that there is something clickable but the UI is not there.

And the Config does not tell me anything what i can do with it ?
 

There isn't any config file. I'll check that. Can you send me a video or, at least, a screenshot?

This is how it looks now for my players.
It has worked after relog. But it made a config on my server.
 

Thank you for your submission. I'm working on it!

Changed Status from Pending to Work in Progress

I don't manage to reproduce the bug. The UI is perfectly working on my local server and online server.

Can you send me the IP of your server?
