second:

I'm asking for help again about this bug. My game crashes when I'm in it and that has caused me a lot of problems both in the dg or boss but this time it was in a halloween sneasel skin and what happened you might ask, well the game crashes and I lose the halloween skin pokemon I asked for help at the time and nobody helped me and now I'm asking again if you can solve the problem (also the one about the game crashing). and how come I'm asking again? well as I said before nobody could help me with that skin error and the first link. I attach photos of the sneasel (if you speak Spanish sorry for what I mentioned in the chat Xd)  

Hi there. Thank you for contacting us about your issues.

First off, I present you my apologies for the delay of response. We at the Staff team do our best to answer every player that comes to us for help as best and fast as we can, but you also must keep in mind that Staff work is voluntary and we sometimes have other priorities outside of PRO. 

With that said, I present you my apologies for the situation you experienced with the Halloween Sneasel. It is extremely unfortunate, we can't know if this was the server crashing, your Internet connection timing out/disconnecting or some other similar issue that caused the crash. In cases like these, we unfortunately cannot "restore" the Pokémon even with screenshots proving you did encounter it. Again, you have my sincere apologies for that unfortunate situation.

Now regarding the Cyan Fire Wings issue you posted about, can I ask if you had acquired them during the 2020 Summer Event? Because as you may already know, these wings were only obtainable during that specific Event in 2020 and weren't available afterwards. I believe there was a glitch in this previous 2024 Summer Event that caused players to be able to get them, but this was an issue on our part and all the Cyan Fire Wings acquired during that time were removed from players's accounts.

I hope the information provided will be useful to you. Again, I present you my apologies for the Sneasel situation and I really hope you continue on hunting to get another. Please always feel free to come back and ask if you have any other question or issue in the future. Good luck in your adventures!

I got the wings before the 2024 summer event, I had them a few weeks before (a friend also took them and they returned them to him) well, and about the internet or something like that, it's not like it changes connections 3 times and the game still crashes. I used any internet and well, about the skin, thanks, even so, at least they answered me.
