I hear you guys and I understand your frustration. These issues are being worked on, it's just that the attempted fixes don't seem to be doing the job.
Making things more difficult is that these are not 100% repro situations, meaning that they are not happening all the time for all players. Please note that I'm not saying that these aren't happening all the time for those of you reporting such. I do believe you.
I will be sounding the alarm on these crashes. If you have error tracker numbers, please post them if you have not already done so. Thank you for those who have provided them.
Thank you CrypticFrost for taking the time to update us on the situation. The knowledge that these issues are being actively worked on is a great comfort. Please pass along our gratitude and appreciation to the devs working on this. And if there's anything else we can do to help track this down, let us know as we have a great many foundry authors ready to do just about anything to get the Foundry working properly again.
Just started experiencing this issue last night. It originally crashed while I was editing a mission. I walked away for a moment to get something from the car and came back and it was crashed to desktop. Tried to get back in about 7 times last night before finally giving up around midnight. Just tried again for the first time today, still no luck. Just keeps crashing. Hoping this can get resolved quickly. Thanks to all of those working on it.
