Thanks to head_victim on freenode irc for help with bughunting and testing, here's another update:

Turious is at rc4 with changes to the engine code to prevent segfaulting when training large numbers of units, and also a fix to 'upgrade strength' to show correct cost in console - some old code meant it was showing the cost for the wrong player!

TSDL is now at rc3 with some changes to the event management to get the keyboard working again... the active widget kept getting nulled out.
