Got a python exception playing as the Mazatl, in the spring spell.... All I've touched is the reqSpring, not spellSpring, so I don't THINK it was anything I did.

The exception says line 3291(should be 3276 for you, not sure though), the line reads "startWar(caster.getOwner(), pPlot.getOwner())". Screenshot is attached. My first thought was that the code tried to have me declare war on myself, but it says 'startWar' is not defined.
Edit: Got a second bug. Deep Jungle isn't supposed to spread outside of Lizard territory, but I had a tile outside my borders spontaneously convert, and then a change back to normal jungle a few turns later. Screenshot is attached.
