Frequent errors with Lab Escape start

[Proxiehunter]

Using build 0831 every time I try to start a Lab Escape from the prison cell I get the error message:

Unable to generate a valid starting location Experiment Cell [sloc_lab_escape_cells] within a radius of 3 overmaps. Please report this failure.

I've seen this error before but never so frequently.

The mods I've been using are:

"dda", "no_npc_food", "novitamins", "elevated_bridges", "a_mutated_arsenal", "Tolerate_This__", "bio_recipes", "CBM_Arms", "Uekibati_mod", "growable-pots__", "eps_cbm", "makeshift_stuff", "Survivors_Lost_item", "food_irradiator", "hydroponics__", "mutant_npcs__", "wandering_masters", "WHALEYHAIR1", "P_Caches", "morlock_village", "deoxymod__", "shrub_mod", "mxoudpcosmetics", "zets_hair_extensions_undead", "Mutation_Changes", "stats_through_kills", "StatsThroughSkills", "ArmUpPAUtil", "ArmUpSurvEx", "makeshift_engine_hoist_mod", "pressure_weapon", "SM", "more_survivor_stuff", "recruitment_options", "amplified_players_features", "aftershock", "Integrated_Fusion_Blaster"

Going to try removing a few more of these that look like there's a possibility they could contribute but this problem highlighted a second problem that I'm going to type up a different report for first.

I removed everything except

"dda", "no_npc_food", "novitamins", "elevated_bridges"

The error persists. Have recent updates done something to remove the Experiment Cell in labs?

It works fine with any other Lab Escape starting position (although sometimes it says it can't find a good place to put my character and spawns me on the entry level), it is apparently only the Experiment Cell spawn that doesn't work and it seems to fail 100% of the time.

Should be fixed with #1369.
