Are walls bugged?

For some weird reason Stone walls for a city (lvl 2 walls) act just as strong as Wooden walls for a large town (lvl 1 walls) I was playing around in descr_walls and adjusting wall strengths and decided to test it out. I even checked in the EDB file to see if the wall strengths were set right and they are!!!

So now if I adjust strength for lvl 1 walls it applies both for large towns and cities!?!

I shot at the walls with Trebuchet (Attack against buildings 110) and I tried to adjust both strength for lvl 1 and lvl 2 walls but both the stone and wooden walls seemed to be as strong. Bug or have I overmodded the game?!?

I tried vanilla and LTC and both show the same resaults, wall strength for large town and city are the same, don't know about other walls though. Could be that this applies only to custom battles dunno, I haven't tested this in the campaign yet

Not sure but I've over modded before and strange things can happen as a result.

Nah, I tested it with both vanilla and LTC and both showed the same resault.
Trebuchet was doing the same percentage damage to wooden wall of a large town and stone walls of a city
