Does the issue occur in the editor or during gameplay?
Gameplay
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
Grid Movement, First Person
Briefly describe the issue you're experiencing:
When a model is equipped the attach points on it will disappear, unequipping and re-equipping fixes the issue
Are there any errors in the in-game debug console or external console window?
No
Provide the steps necessary to reproduce the issue:
Create a model with attached objects, equip it in game as an item, save and quit the game, load the save.
Provide a download link to the bare bones project (strongly recommended if it's an in-game issue, since this helps significantly when attempting to reproduce it; the report will also be given more priority in this case):
Will be reproduced in any project
