I'd say it's about time for a hard drive failure, a trip to the hospital or death in the family announcement. Just WEG dev things when the deadlines are long passed.
I'd start with a change of place of residance which includes a looong period of new house renovation of course.
Then a hard drive failure.
After that...why not divorce? Or if not for drama then let him be super busy with a newly born kid.
Then a long period of silence...and the cheery resurrection of the game.
...which includes (of course) a complete remake of the game. That is still in its early stage obviously. Old version to the trash bin.
Hospital or death stuff...dunno but I'd just start with a hard Covid.
Then I'd add some mental problems due to all the aforementioned problems plus burnout.
In the meantime the publisher goes bankrupt.
And we have a Steam release by...guess when? ^^
