BUG: Sims missing from the portrait panel

 

Problem

• My Sim is not shown in the portrait panel anymore. All I see is a green square
• My Sim is not shown in the portrait panel anymore at all. 

Causes

• Sim Corruption probably caused by two Sims with the same ID running around town. This can happen when Sims either occur in the relationship panel twice (double relationships) or if they return with clones from the vacation. 
• ... 

Solution
If you have this problem, you should either start using mods or move your Sims to a new hood. You can try if moving out and in gets your Sims back but I don't think it will in most cases.

Mods, that help with the issue

• Overwatch and ErrorTrap are probably both essential in solving this issue. ErrorTrap can clean up the errors that lead to the problem in the first place and Overwatch can help prevent them again. If ErrorTrap does not recover your corrupt Sims completely you should try reset lot on MasterController or use the Sim Deleter method by Trif
