In the middle of working on a mod, so, savegame and mods are currently not available to share.
However, I can walk you through the cause of the issue.

1. Mod a spidertron to require a burner fuel source.
2. In a game, fuel a spidertron. Add logistic request for that fuel.
3. Save and exit.
4. Remove the change in the code for Spidertron to need a fuel source (It's an option in my WIP mod.)
5. Load game, crash.

Log and Dump included.
I can include a savegame if requested later, and a link to my mods.

Error LogisticPoint.cpp:665: Check distribution state error: available + targeted for pickup doesn't match actual count.

Currently having dropbox space issues, so no savegame right now, but... get yourself my warfare mod, which needs my library mod, and that should give you the quick option in mod settings to give spidertron a fuel source (there's 5 spidertrons in total in the mod, spidertron and heavy spidertron use nuclear power, where the other 3 use burner power... if you choose settings that have them requite fuel.)
The vanilla spidertron is set to use nuclear fuel.

Somebody edited my original message (rather than respond to it) to add the green text, and the title, which says it's a logistic issue.

Thanks for the report. It's now fixed for the next release.
