i tryed to change DB block IDs, but with no effect.
then i was suggested to change "AutoAssign" value in RP2 config from 0 to 1, and it actualy woked, game launches, and everything seams to be working.
DB blocks are avalible, but after another launch "AutoAssign" value resets back to 0, and game crashes again (after setting it back to 1 everything is fine AGAIN, and map seams undamaged or corrupted and DB blocka are present where i left them)

Doe anyone has any ida how to fix this issue ? its annoing to switch that value all the time and risking world crash or corruption... but i dont want abbandon DB either, those blocks are just so cool

thx

To clarify, you weren't having any problems prior to trying to add this other mod?

no

fixed: it spears that this is the way RedPower2 says there is and id conflict.
swapping some IDs solved this problem

 

[Slind]

is there a way to see wich id caused it ?

 

[Karimiri]

should be in the crash report. then you go into config files and compare those 2 mentioned there
