Resource display/counting issue

[Toranth]

In my current game, something seems to have gone wrong with my resource display.  It shows 999,999 crystal, but when I try to spend it, the total only drops a short way (to 950,000 or so) before going into "Resource outage flicker mode" - when engineer support lines turn red, stuff doesn't get built, etc.  I'm not sure if the display is wrong, or what.

I checked Mantis and didn't see any similar reports, so I was going to ask:  Is this something other people have seen, and does anyone have any ideas on how I might fix it?  Restarting doesn't help.

If no one has any ideas, I'll put the report into Mantis and this game'll have to wait.

1) Are any of the units (including the spacedock) in a control group that has resource spending limits?
2) Do you have Engineers Do Not Assist Large Projects value up high?

I did have a resource limit on my Mercenary Docks and half-built Superfortress, but this bizarre behavior was impacting everything I tried to build.  It even impacted saves from earlier, where things had been working fine.  Unless everything that could build was considered part of that control group, I don't think that was it.

However, you inspired me to try deleting my configs - didn't help, but deleting and reinstalling the entire game DID fix it.  Strange, but I can play again.
Thanks for the idea!
