Error when attacking or rolling damage

[Lector]

Hi,

I have played a few sessions with my group so far. It seems that some issue causes the characters to 'corrupt'. When i roll Attack or damage with a weapon with some characters i get the following error in the chat:

java.lang.NullPointerException: Cannot invoke "net.rptools.maptool.model.Token.getProperty(String)" because "token" is null Fehler beim Ausführen des Ausdrucks classes=getLibProperty("Class&Level","Lib:"+tokenName). Error-Trace: Dice Roller process@Lib:Character <<< macroLink
