So, I'm mostly writing here for two friends of mine who are on morpher. Their virtual eth balances and are now 0 when they try to make a trade, even though it isn't 0.

I don't have the same issue, but when I tried to login to morpher this morning my metamask had completely reset itself. I had to add my account again. Perhaps the last issue was more of an issue with metamask itself, but still it's a strange coincidence.
It seems the issue is lokalized to trading crypto. They can trade stocks on morpher just fine.
This is what one of them saw:
