overhauled techtree crashing FW 2.78

[con dodgy]

i'm attempting to overhaul the FW techtree so that it incorporates some futuristic techs. the structure is similar to that of CTP2..

but in order to do this, i've been forced to use the extra U1....X7 techs in the rules.txt.

now whenever i try to use this rules.txt in the game, it crashes. i can load a game and view the new techs, but then it will crash when the turn ends.

i've checked and rechecked rules.txt quite a few times and i can't pinpoint the problem. i'm sure its the techtree that is the problem.

here is the tech portion:

any help would be greatly appreciated

Did you use Notepad to alter the RULES.TXT?

Using Word will cause Civ to crash.....found this out the hard way.

Aside from that...."stepping" through the tree, one tech at a time, to make sure you haven't messed up a pre-req or two may find the problem.

Good luck.

[BeBMan]

Can´t say what the problem is, but, if the scn chrashes immediately after the start, I use a simple step-by step-method to find the error.

Take the standard FW rules file, then:

-copy the first customized techs (let´s say the first ten) over the first original techs.
-start the scn, if it runs well, copy the next ten techs over the next original techs, start again and so on...
-if it chrashes, you know the problem must be in the last copied ten lines...

God help you my son. Tech Tree problems can be one of the most difficult to troubleshoot. It took me three days once to discover that SF1 was used instead of SFl. Typos, missing punctuation, the dreaded logic loop, failure to properly account for Future Tech, and others make this a devilish problem to ferret out.

If you are certain it's not a typo or transposition, than the only solution is to map the whole tree out on paper to ensure you haven't created a logic trap (an advance from later in the tree used as a pre-req earlier in the sequence). This will also allow you to verify that Future Tech exists at the end of the tree where it belongs.

Bebro: Your method will only work if all that's changed is the title of the advance. However, it looks like most of the pre-reqs have been swapped around too, so your method is almost guaranteed to cause a crash right from the start.

[Theben]

Good luck. One time my game kept crashing because I had unwittingly deleted a semi-colon at the end of the tree. You will need to be very thorough in your check.

[Hendrik the Great]

This may seem stupid but have you done a spell check of the entire rules.txt? If in example the abbreviation for an advance is Mys and you wrote Msy or mys that could be a problem.

Just a thought though...

It would appear you have made some mix ups with ToG and Hor

If I read and understand your tech tree correctly then you need to exchange the lines for Tool Making and Horse Riding.

It is always adviseable to make sure the tag at the end of each line corresponds with the tech location (for your own sake - the program don't care).

You have a technology loop with E2 and Cmb (Internal Combustion and Mass Transit).

Ooops - spelling
