My latest savegame crashes during load, possibly just before game is presented. I've also experienced odd behaviour with saturn traps after loading a savegame. Some plants are in a state where they have critters inside them (That is, content information box shows a critter) but they don't appear as a closed trap and no info about when harvesting should be done is available, may be related, maybe not. No mods, vanilla Spaced Out.
I experience this as well. My workaround until it is fixed is by using a Duplicant Motion Sensor to activate the well whenever a dupe is near it.
