well i had my rant ,stomped off in anger,took my ball went home, ect.apologies to those who got offended.

now to business,

1.i read o lot of posts that say, "we cant fix it ,its hard coded,ie ai behavior we have to wait for the devs" ok fair enough but if people wrote this "hard code" whats to stop modders from rewriting the code? is it locked or somthing i am not aware of?
2. what is this refrence to "bernard"? i see its some kind of inside joke,could somone please enlighten me?
3 if people are waiting for a magic patch that will fix all the more serious "issues" in the game why cant modders put out a patch? they obviously are smart people. is there somthing stoppng said efforts?
4. why does this game cause so many diffrent behaviors? example some people get stupid destroyers, while others get lethal ones,some ppl get periscope depth and crashdive no problem whiile others get a one way trip to the bottom of the sea?or diffrent behaviors on one machine from game to game? this confuses me greatly. i would think that a bug or issue would be experienced all the time on all machines (excluding diffrent platforms) . maybie diffrent processors?,example few years ago most games seemed to be written on intel chisets,i remember seeing patches from like amd i think it was the amd people hs to put out the patch,not the game s publisher is something simelar happeneing now?

please exuse a dumb old man and dont flame just answer please
