Not sure why it happened, but I did some testing and it happens with one specific requester chest. In the save file the player is looking straight ahead at the requester chest and you have to use a destruction planner for the bug to happen.
Log file is from the game crashing while trying to change the requester chest to a storage chest. All I wanted to do was to see how much 4,3G repair packs would look in my logistic network...
Edit: it was not possible to remove the repair packs by hand or robots. That just kept duplicating repair packs in quantities of 100 from the 4,3G quantity. The Requester chest had to be destroyed with a weapon for it to be removed. Game worked normal, save and load, after destroying the requester chest.
