My game loads and doesn't launch after the update

21.589 Info PrototypeMigrationList.cpp:194: Activating migration WideChests/WideChests_5.0.0.json
21.716 Info PrototypeMigrationList.cpp:194: Activating migration WideChestsLogistic/WideChestsLogistic_2.0.0.json

Is it normal for this to take so long (more than 10min at the time of writing)?

Ok after more than 20 minutes the game starts x)

Depending on your map size it could take a long time...for each entity on the map the game has to check 48000 entities it might need migrate to. But this is done once during loading a map after a mod update. I suggest you save afterwards so you don't have to do that again :D
