Are you putting tape behind it first before laying on the mud BP? That might cure it
It’s was taped originally and cracked. Fixed it with tape again and it cracked again. Taped again, tree falls on house, cracked again, just kinda foo fooed it last time. I’m thinking something flexible.
I think there is a lot of movement there. I hear creaking and cracking in that room. Especially in the morning when the sun hits it.
