there a bug within cobblestone cause the AEC bus (maked in 1942) couldn't go over the cobblestone road - the weight for this road was 8t while bus weighed as 9t - the cobblestone road normally can handle heavy loads as today - but can't accept the modern lorries - the Max load for cobblestones that built before 1950's was commonly had limit for 20t which should be specificed in simutrans - some places such old cities (Tallinn) do have cobblestones but their limits are normally around 20t or more
but due i can't play the new map to get more feedback on items because its crashes when i start new fresh map which i already created urgent bug report for james to look at it
RSDWorker,
I forgot to look into the cobblestone road issue (although try using tarmac roads instead), but I have now released Simutrans-Experimental 9.0 and Pak128.Britain-Ex 0.7.1, which fix a number of bugs from previous versions. Let me know if this makes things better for you!
ok i will write the report for version 0.7.1
