NullPointerException when trying to move waypoint

FM-96 opened this issue 2 years ago · 0 comments

When trying to activate a waypoint with a signature that has previously been used, an error is thrown in some cases:

(1. and 2. work as intended, and are just listed for comparison.)

Previous waypoint with that signature still exists in the world. -> You get a message telling you that signature is already in use.
Previous waypoint with that signature had its signature changed. -> The new waypoint is activated with that signature.
Previous waypoint no longer exists (i.e. one or more of its lapis blocks have been removed). -> The below error is thrown.

java.lang.NullPointerException: Cannot read field "status" because "conflictInWorld" is null
