Valdo abyss puzzle bug (lost foil nimis)

I just run a valdo puzzle map with abyss that would reward me a foil nimis my character is quite strong so i decided to go for it below i will post a picture you can see i completed the map and there was no chest anywhere on the map with 0 monsters remaining , there are also sirus storms in the map which i don't know if it hid the box or something bugged with the abyss .


I was going around the map all the time trying to find the chest and couldn't find it anywhere. I am pretty sure you can check my logs as well. My character's name is DefSparrow (account name Haxforthewin).

I am hoping that you can find the chest and if it is possible to have my nimis back

Below is a picture showing that there where no monsters remaining

I cleared the whole map and run around for like almost an hour trying to find the chest and couldnt find anything.

Thanks in advance
