Thanks fro the clarification. Sorry for my testiness, but I actually have a pet aversion to the excessive, to my mind, use of abbreviations around here. It seems to me to be all about making the message easy to type and nothing to do with ensuring that it can be understood.
I had a single episode of repeated Civ3 crashes a couple of months ago. Prior to that it had been very stable. I reinstalled it from the ground up, including all the GOTM files from 16 onwards. Since then it's reverted to its previous completely stable behaviour. That experience was what prompted me to build the GOTM installers.
Aside from that episode there have only been a couple of specific situations caused by known errors in the pediaicons file, and then only at the end of game when the victory celebrations are supposed to begin. I played Gotm23 to completion with no crashing problems, other than the fact that I had only reached 1200 AD by September 30 and had to commit suicide to end the game
If your Civ3 was unstable during Gotm23 then it probably isn't going to get better by itself. I recommend you reinstall the application, and apply the Gotm23 full installer to it, followed by the Gotm24 incremental installer.
If you think the current crashes are occurring at specific points in the game, such as diplomatic contacts with certain civs, then you should PM Cracker with the details in case there are problems with the current game files. No-one else can help you there without risk of a spoiler.
The installers just overwrite anything that's there, so they would repair any errors in manual placement. However, I would recommend starting with a clean install from your CD plus the 1.29 patch, as there's no guarantee that your problem is with a GOTM file.
