They already finished their swap last Oct 2020. Don't know if you can still get a hold of them and explain the situation.
Based from their blog, those leftover STORM tokens are converted to STORMX.
Now, I don't know what will happen to individually-owned STORM.
Didn't expect also that this project will survive long in crypto.
Yep. Most of the Storm tokens have been swapped successfully but a small proportion who missed the swap date urged the team to reopen the swap.
And the team has come up with a solution by allowing StormX users and community members to decide how the swap should be handled.
