The PressureWarp plugin that is used by the warps in the spawn ships is very old. It hasn’t been updated since 2015 and while it was fine for a long time, it causes Java errors and crashes with the latest Minecraft server every other day. Same goes for Dynmap. Its up to date but these versions are always Dev versions, aka not finished products.
To combat this I’ve created a script that checks if the server is down every five minutes, so at the most anyone will see is five minutes of downtime.
I’m looking into an alternative to PressureWarp but I already know there isn’t one for Dynmap, as its a unique plugin.
