- Fix: Do not look in every direction for tunnels when building one, one direction is enough (r10258) - Fix: Take the age of the front vehicle for station rating (r10246) - Fix: Terraforming wipes out canals. Now you always have to remove the canal before terraforming, instead of "just" removing the canal [FS#594] (r10240) - Fix: Only 2 trains could crash at one time as collision checking stopped on the first hit. This could technically cause desyncs in network games as the collision hash order is not guaranteed [FS#892] (r10222) - Fix: Land under foundations was terraform when it shouldn't be terraformed [FS#882, FS#890] (r10219) - Fix: Some NewGRFs use the same (unused in the "current" climate) sprite IDs. Normally this gives some artefacts, but when one NewGRF expects it to be a sprite and another NewGRF overwrites it with a non-sprite nasty things happen (drawing a non-sprite crashes OTTD) [FS#838] (r10109)
