Well.............. That is probably a big part of it. When I open a new Hub, I will create anywhere between 20 and 80 routes at once...... usually with the game paused. I will avoid that practice in the future.   Thanks.

I will make the pledge; it will be worth it to not have it crash anymore............. or even half as often. Will I receive a KickStarter notice, or do I have to remember to log on in late September?  Also, is there ANYTHING I can do to reduce the crashes in the meantime on my PC, such as adjust Settings, clear cache every hour, change screen resolutions?

STILL Crashing on Save.  Want to fund your KickStarter for $1,000 USD, but need some assurance the new version will be more stable than this one.

Is your Kickstarter account up yet?

Still having problems saving. Yesterday's save appeared to work fine. When I load the file today, it runs for three game-days, and then freezes. Any assistance you can provide will be appreciated. Also, is your KickStarter account up yet? I would like to contribute to the development fund. If it is not, how else can I contribute?

Still having problems with saves. Save yesterday appeared normal. Tried to load the file today, and it runs for three days and then freezes. Also, is your KickStarter account up yet?  If so, I would like to contribute to it. If it is not, is there another way for me to contribute?

Crashed in mid-game; It has done this twice today, and twice yesterday.

Post Deleted; thanks for the warning. I uninstalled and reinstalled yesterday........... right after I took uninstalled nahimic3 from my computer. Some blogs say that nahimic can cause crashing.  I will try to run it some in the next few days, and see how it does; If it crashes again, I will send you the log. Thanks.

Great... Thanks !!!

When do you expect the next patch will be released?

Thank you.

Powered back on after dinner, added FLL as focus city, bought facilities there, created routes from FLL, tried to save, and ......... Crash. :-(        The log says:

Powered back on after dinner, added FLL as second airport, and set up routes; tried to save, and CRASH.  :-(        How shall I send you the crashlog?

I don't know what particular type of Black Magic you applied, but it was HIGHLY effective !!! Have the game back to (as closely as I can remember) where it was crashing on Save before, and it is working flawlessly.  Thanks again for your prompt response/resolution of my problem !!!

Thanks for the prompt response !!! I will download it now, and give it a try.

The game is installed in its own folder on C: , if that matters.

Typo: Computer is 9th gen Intel I-7

I recently contributed to the development fund, and received a link to download 2.14 Patch J. Since doing so, I have had a problem with the game crashing on Save; even though it is a lightly-loaded game. Custom Airline, out of Dallas Love Field (no other focus cities or hubs, fleet of thirty-one 737-200adv, serving 79 destinations. AI airlines (2) have no routes yet. Two years into scenario that started in 1975. Computer is I-7 (4th gen) with 8gb of ram, 512gb SSD, and a GEForce 1gb GTX video card. Any idea why it is crashing when I save? It will show the "failed" save, and if you try to open it from the "Load Saved Game" menu, it crashes the game again.
