The timed event works fine, but when I try to trigger one manually with dtevent in console I get "Event failed to start! Unable to obtain a valid position. Please try again."

I noticed that your config does not have the hex values for the colours, are you using version 1.3.1 as that was changed after game update before the last one to show hex values

The plugin converts the values to hex on the fly when using them in messages. I'll have the config update itself to hex values automatically in 1.3.2.

Your config looks good to me. I don't think I will be able to reproduce this bug without some more details. So please specify anything you can think of. Your map size, amount of entities on the server when this happens, etc. Anything.

I've tested this thousands of times before releasing it so I don't know how this is happening unless it's an issue with your entity count being too high.
It just started working on it's own again.  I didn't change anything.  I think it may have been a map issue.  Lots of bugs after the latest procgen update. 
Good to hear.
