[V7.2.0 - geoscape] - crash to desktop from geoscape around day 112 --- day 114 if cleaner base is not yet destroyed - NotSupportedException : A fatal error occurred during Update[] - Override Path can't end with an indexer. Path: 'selector.Targets.[0]

Description

crash to desktop from geoscape around day 112 --- day 114.

 

Error from crash_info is

NotSupportedException : A fatal error occurred during Update[] - Override Path can't end with an indexer. Path: 'selector.Targets.[0]

 

Potential workaround for players until this bug is fixed

Immediately assault and destroy the cleaner base on day 110, before time advances to day 112 -- 114.  Doing this let my campaign progress to day 130+

 

What Happened

After updating game to v7.2.0 I resumed my campaign (day 107).

The cleaner base was revealed at start of day 110, I clicked "accept report" and the game did not crash (improvement over V7.1.0, thank you).

I did some more stuff (setting next engineering project)

On day 112, a destroyer UFO appeared, I shot it down & collected the bounty (UFO delegation)

Shortly after that, while still in geoscape, game crashed.

added potential workaround

I loaded an earlier save, the scenario played out slightly differently, UFOs took different flight path & I didn't see the same destroyer UFO appear, but the game still crashed around day 112-113.

Here's a second crash report:

Shalako17 shared a report of what sounds like the same symptom on steam discussion boards

CTD after latest update
Can now resume after cleaner base discovery, but CTD day 112/113 no apparent reason
