Depends on the Devs. If they will extend the time for the event they will for sure announce it.

The 4th protection slot is not available in any sort of containers (and I don't think they will ever add it to them) You can obtain the 4th slot within tanki funds (for hitting the conditions) or in mini events, like the current one:

That's all I got of information based on this topic... if you want to suggest an idea, then do it here: https://en.tankiforum.com/forum/182-ideas-and-suggestions/ (make sure to read the rules before submitting a post)

Should be the right place to discuss about challenges and their rewards.

Its either "hacking" or something else. Its cursed by ur point of the view and his point of the view. I think its called "de-sync". In ur point of view you can hit the player like you did before. But in the view/perspective of the other player you just hit, it could look else like. Almost the same theory is, when you are about to make someone miss, with ur own shot. In your perspective you made him 100% miss, but on his its not quite like that and hit you without a problem. I would not say to someone that he is using "hacks" right away.

As far as I know, its quite enough if you give the information on which month and year you created those accounts. Try to talk to the support again. Can't do more.

You can apply as eSport Official here, if they looking for new officials. After this tanki fund (Tanki bday), they will announce another Tanki Fund especially for the Summer Major. The winners of the tournament gonna receive those rewards:

Pro Battles are enabled again.

Ofc others got it ... not yet. Just relax. We'll get those rewards. No rush.

After buying the special offer to switch teams, it needs some time to let you know which team you're joining. So, just wait a bit.

It takes some time. Dont worry we will get the prizes.

There is no exact date for the next tanki fund.

True. Its prolly a question of time. Also possible as a battle pass reward. But depends on the devs.

Yes you are right. Got a bit confused with the question. LOL You would've had to get 50 Stars on the past stage (where jamming vulcan was available). So if you decide to join right at the moment, you would just receive the prized of the current stage. No.

In that case you have to buy the special offer to participate in the event and also have to earn that amount of stars So, you would have to get 50 Stars earned and you have to be in the winning team.
