The new smithy sound effects (of Tada) have been replaced again by the older sound effects.
I don't see anything in https://bazaar.launchpad.net/~widelands-dev/widelands/trunk/revision/9068 that would change those sounds.
Do you know which buildings are affected, so that we can look at the revision logs of their files?
I think all weapon smithies, ax factory and warmill, maybe even some armor smities, and tool smithies.
The soundfiles itself don't have changed, although with the TADA branch only the smith_00 and toolsmith_00 sound has been changed. However there are smith_01 and smith_02 as well as toolsmith_01 sounds that might be played instead (perhaps due to variety reasons?)
The Tada sound effects don't appear anymore, and the old sound effects are not desired because they are unpleasent, so they had been removed once - which was good.
