We took a break for six months and then started playing 3v3 duels again – two questions arose, and I would be grateful for clarification.

1) The Lava Dragon has fire resistance listed in its properties, but it still explodes on a fire trap and gets hit by a fireball. Is this a bug on my end, or is it intentional by the developers?

2) The Cerberus (the second possible upgrade) is supposed to bite three adjacent cells, but I encountered a situation where it bit five creatures, and some of them were even one cell away from it. Again, what's going on?

Thank you in advance.
