I dont know what happend. I tried to use the server status variable but it didn't work, so i updated the plugin to the latest version.

Here's the console error that keeps spamming:

Server thread/WARN [HolographicDisplays] The placeholder {time} registered by the plugin HolographicDisplays generated an exception while updating. Please contact the author of HolographicDisplays

The server where this came from is running on 1.8.8 BUT i my SMP server that runs 1.14.4 spams the same console errors. I normally don't post things like this so let me know if i forgot something.
