sure @Madara

That really sucks, I've wasted so many crystals. Who wants such a terrible update? Really sad to see tanki now, it was such a fun game. Whatever, thanks for your help ?

I'd been playing tanki online a long time ago and I've recently started playing the game again and managed to rank up to the rank Major General, which means I'm now able to get Mk6 hornet and viking. I upgraded the two hulls to Mk5-10 before ranking up. Now it says that I have to pay an extra 97'000 crystals to upgrade to Mk6. Is that a bug or is there a way to upgrade the hulls without having to pay that much for it considering that it does not change anything about the power of the hulls? Or are the developers just wanting to scam me? Thanks for your help in advance.
