I took screenshots of a lot of the things on my island 40 mins or so before the conversion started yesterday, and looked at everything again once we could get on again last night..... My oil queues particularly had shot up to 8 thousand odd days.... Thankfully, today they have settled to more reasonable numbers, but they are still different from expected.
I have not included the template info as the numbers have NOTHING to do with my setup. The game runs and plays, it just converted some things during the migration. As a bunch of the buttons have been reversed in the dialogue boxes, I tend to guess that the coder has attached the wrong frontend field to the non-matching backend field.
I would expect somewhere around ONE DAY's difference in the queue (minus whatever hole the maintenance outage stole), but NONE of my queues are.
The before shots are around 20-Jul 13:20 AEST, and the after shots are around 21-Jul 13:06 AEST
Oilmills (Looks like almost a whole extra day has disappeared)
Refineries (Looks like the queue duration has been changed to oil PLUS fish times rather than oil PLUS stalks)
Produced oil between the snapshots:
Snack Stands (Looks like and extra day and half disappeared)
Blacktree (No idea what this extra time could be explained by)
Sickbay (Well each medipak used to take 14 days, so maybe that's the 14 days-ish difference in the queue? but it shouldn't be!)
