Hey! Attach your dungeonData file, please.

Here

npcData.json playersData.json eventData.json DungeonBases.json

Your data files are empty. Is the plugin loading normally now, or is there still an error?

still errors

Is this the same error? Please find the line in the code:
if (cardReader == null) return;
replace it with:
if (entitiesList == null || cardReader == null) return;
Please let me know the results

And where should I change that, i.e., in which file?

Let me try to send you the finished file in a PM

ok this is my discord name twitch_vinni_tv_

Changed Status from Pending to Fixed

Changed Fixed In to 1.2.2
