How do I describe this error....I CAN"T CONTROL MY SIM ANYMORE.The Sim becomes immobile and there are no interaction available.Also, the square that displays the Sim's face is replaced with a blank green one.In general, that sim is like non-existent except for the fact that his tab is still there.How can I fix this? I doubt that this is a mod's doing because I only have 1 mod that is the Sim transformer by Treeag which is claimed to be compatiblt for LN.Plz, appreciate any help.
