When i select a custom skin from a custom skin pack, and attach a cape to it with the character creator, it will not save. When i restart the game, the skin resets to default, and two new default characters are created. This happens without attaching a cape to the skin as well.

Here is a video of it happening: https://drive.google.com/open?id=162vNUJ-qWARm9C7NhdQom8QuZV6K6bdY

How to reproduce bug:

1 - Choose a skin from a custom skin pack located in /games/com.mojang/skin_packs

2 - If you have the Founders Cape, attach the cape to the skin from the custom skin pack

3 - Restart the game and you should find that the skin has been reset to default, and two new default characters are created

Please fix this bug, it is extremely annoying

Note: this also happens when minimizing the game and resuming it.
