@soix The Post from @recordguardian a very appropriate name, has made it clear what is a ambient environment condition that can cause a warp to occur.
When hands on with the LP’s, this is one more consideration to be checked for and avoided, for this condition to be created in close proximity to the LP’s.
I don’t think there is an LP owner from their heyday of usage that has not had a LP warp from leaving an Album local to an external window that receives Sunshine.
I may have even been expressive of a wicked nature, where at a certain time, exposed a Sibling Brothers Album or Two to such a condition 👹
