Menu doesnt load for some players sometimes.

This is a screenshot taken by a player. They did /st and the screen darkens but never loads anything.

Additionally, some of their skills sporadically don't work. For example, 6th sense won't work until I reload the plugin, or the player logs back in. Same for bandage perk, magazine size perk.  Any ideas?

It is happening to me on occasion too. I just logged in and tried to open skill tree. One thing I noticed is that the XP bar does not show up when I log in, which then leads to this empty menu.

Additionally, this is in the logs:

Looks like an issue with your server mate. All plugins that listen to the hook are throwing an error.

Any errors in console when st is run?

no errors in console with /st. I disabled a few plugins and no longer get all those errors --  I'll monitor over the next few days to see if that resolved this

Worst case delete your config and have the plugin gen a new one, and see if that fixes the issue.

Same with the lang file.
