Our living room ceiling cracks every winter. This year however it is worse than we have ever seen it. We mentioned it to our landlords and they are working on solutions. And to make matters worse there is also cracking in the kitchen. Here are some pictures. The first two are by our front entryway.
This is all the insulation (supposedly they insulated ceilings with woodchips at some point!) that fell in about a week or so.
Then the kitchen started cracking too.
