New player here (only two months or so), didn't see any mention of these specific bugs, so here they go:
1. Selecting my game pops a Error in cboGame - Overflow. Still able to select, start and play the game normally.
2. Attempting to duplicate a 1mt station class caused an error and the station didn't duplicate,
didn't think much about it at the time so didn't record it. Tried to duplicate it now - attempting to copy design of a 1mt station causes an Error in cmdCopy_Click - Error 3163 in DAO. Field field is to small to accept the amount of data.
After that, opening the class design window started causing 2 errors that repeat several times, after which the class design screen works without any (noticeable) bugs.
The errors are: Error in PopulateClassList - Invalid use of Null and Invalid property array index.
3. When tried to tug my first terraforming station into place, detaching the station over Venus made the station TG glitch out into the warp: the station appears in the ship list without a task group (blank field), the TG itself does not appear in the TG drop down, ticking tasks groups in destination options displays all the normal TGs plus a blank field at the top.
Any action that displays TGs causes various errors:
a. Switching to Sol system pops a Error in DisplayFleets - Invalid use of Null, Error in ShowFleetList - Type mismatch (generated by TreeCtrl)
b. TG windows pops PopulateFleetList invalid array index, invalid use of null, cboFleets invalid null
c. In general, anything to do with TG pops some combination of the above errors.
The station does terraform Venus, though.
The third bug is the game breaking one, as the other errors don't really happen all that much. The terraform station TG causes these error popup in Task Group screen whenever the target destination list includes TG's in sol, so almost all the time, and in any screen refresh in Sol (zooming or panning or anything else), together making the game unplayable.
Deleting the Terraforming Station from the ship list fixed this (guess that also deleted the ghost task group), but I dont know yet if this will keep happening to all my stations/ships when they detach from their tug, and I was kinda hoping to build lots of them so thats a real shame
EDIT: Build a second terraformer station, when detached from a tug threw the Error in DetachShipType - Error 3163 in DAO. Field field is to small to accept the amount of data". Will try with a smaller station next time.
