Recently when opening the timeline I have been hit by an "Unexpected Application Error" that removes me from the environment and references a TypeError of "Cannot read properties of null (reading 'title')".
When I am able to access the timeline, it occurs if I press the previous event arrow more than once.
This also seems to line up with an inability to edit the timeline when it is viewable. Several Events jumping back to previously saved states rather than saving new changes.
Steps to Reproduce
For Error Screen
Open any timeline in the world Nonvyrox
If the error doesn't appear immediately, press "Previous Event" button twice.
For Inability to Edit Events/Ages
Open any timeline in the world Nonvyrox
If it can be opened, edit any element of an event on the timeline
After a few moments it should snap back to previously recorded data
