I have found a bug in the flash version of your game, in the tutorial, during the step where your suppose to entangle the cricket thing and destroy the other base.
Here's what i did to reproduce the bug
1.login under a brand new account or guest to start the tutorial
2.play until you reach this step which instructs you to place your own grove
3.play through, and lose during this step to the AI
4.Restart this step, and place the grove middle space, at the center of the spaces you can place it
5. your grove goes boom instantly, and you have to start over
I'm on Windows XP Professional SP3 using Firefox version 3.5.9
I have a screencap of the message, it shows that i haven't done anything except place the grove and i lost already.
