Here are the steps for an issue:
1. Put on thief's costume.
2. Talk to Gusto and Fatale (they think Tilo is Tulong)
3. End the conversation, go to another room (or barrel) and take off the costume.
4. Come to Gusto and fatale again
Result:
Mice still think that Tilo is Tulong
Expected result:
Gusto and Fatale think Tilo is Tulong only when he wears thief's costume.
This issue is actual for all costumes. For example if I put on recruit's costume and take it off guards still think that I am a recruit.
Another issue:
1. Open the inventory
2. Put on some costume
3. Take it off not closing the inventory
4. Try to put on the same costume
Result:
nothing happens
Expected result:
Tilo puts on the selected costume.
