Here's a minor issue with the 10.0 branch that I didn't think worth including in the main pre-release topic, but nevertheless seemed worth reporting for the record.
10.0 is unable to open most saves made in xml format. It gives the following error:
FATAL ERROR:
loadsave_t::start_tag()
expected "tunnelboden_t",
got "grund_t>
รป []"
Note that the "[]" here is a square box in the error. This error does not occur in other save formats.
The problem doesn't seem to be with the saves themselves. I tried making an xml save of a game in 9.12 and then opening it with 9.12, and this was successful. However, this 9.12-created xml save could not be opened in 10.0. Similarly, xml saves created in 10.0 give rise to the same error.
I can reproduce via the following steps:
1. Set save format to xml in simuconf.tab
2. Start a new map
3. Build a tunnel
4. Save the map and close Simutrans
5. Open Simutrans and load the save map
6. Error!
Here's a pak128Britain.ex 0.8 save to demonstrate: http://dl.dropbox.com/u/61716/tunnel.rar
Hmm, that's very odd - I haven't changed anything specific to XML saving between 9.12 and 10.0. I wonder whether this is a bug from the latest Standard nightlies...?
