That is what the
means. The game can not find the Mesh for that item. Since it is all of your containers, the mesh for those containers are bad, or missing.
One of the problems with Mods, is that you may loose some of the Meshes. This usually happens when several mods are changing the same item(s). When adding the new meshes, it may overwrite the one that you need, or you might even have several of the same ones, and the game doesn't know which one to use. Load order can also affect this.
1.) If you uncheck all of your mods, and are still having the
for containers, then you may want to load all of the data from your mods again.
2.) If you uncheck all of your mods, and then recheck them, one by one, until you start having the problem again. This will help you to identify which one causes the loss of the meshes.
You can have all of the Official Patches/Updates, and the Unoffical Update. The Unoffical Update fixes the bugs the Offical ones did not fix.
