1.07 CTD
I never had crashes before 1.07, but after starting a new sandbox game it has happened three times now and I have barely started, maybe 100 turns in. It is all related to the tactical battles versus Creatures, either initializing or during, apart from that I don't see any relation. The latest one happened just after capturing an independent City and then entering tactical battle versus nearby Spiders. It Autosaved just prior, reloading and fighting again results in no crash, go figure. Here is the Debug report via pastebin http://pastebin.ca/1935695
