Builder/Supply Ships Bug

[Bollen]

For some bizarre reason, my builders and/or supply ships keep resetting their drones when I restart a game i.e. I fill all my ships with defence drones and a few repair drones. All is fine until the next time I start the game, at that point they've all changed to a random amount of repair and cargo (or building) drones.

The devs cannot investigate without at least a link to a vanilla save showing the issue. Here's how. You didn't mention if your game was modded.
