Greetings,
We understand that the mechanics of Twintania are a very hot topic in the community currently and I would like to clarify a couple of things.
First, I would like to clarify something about the bug report flow as we've seen many comments about this in the past. Bugs that have been moved to the "Accepted Bugs" forum are those that have sufficient information to be investigated. Although a reported bug was moved to the "Accepted Bug" forum does not mean that what was reported is an actual confirmed bug. Apologies for any confusion related to this process.
Next, there have been a lot of comments about how surviving Twintania's "Twister" ability is seemingly random. Please know that it is not random and that the development team has adjusted the difficulty of this battle to be of the highest level that is in the game currently. With that said though, it was still designed to be beaten. While we definitely cannot comment on strategy, we believe that a valiant group will be able to defeat Twintania.
