Issue: Factorio 0.15.6 crashes during loading of select old maps (log says "139.960 Info Scenario.cpp:133: Map version 0.14.13-2") that have had mod(s) installed. Crashes possibly relate to migrating a save from 0.14.13 with the mod "Warehousing 0.10" installed... to 0.15.6 vanilla (no mods installed.)

Expectation: Factorio migrates the older map file to vanilla (with potential loss of modded/outdated in-game items) but does not crash. Tested other maps saved in "Map version 0.14.13-2" and they migrated without crashing Factorio (as expected.) These loads are also displayed in the attached (and unedited other than filename) logfiles.

Reproduction: As the savegames are migrating from oldversion-modded to 0.15.6-vanilla. No non-hardware specific circumstances are expected to be needed at this time.

Your save(s) were saved during a specific version of 0.14 (0.14.13) that causes a crash if any prototypes are changed when you load the file. If you load it in any future version of 0.14 and re-save it you'll be able to load it in 0.15.
