attack mode 1 and session restore?

Hello!

Is there some technical reason or just a bug that prevents me from doing a --session blaha --restore when I created the session with -a 1?
Currently combining the current dictionary and when using --session blaha --restore, it starts all over again.

This is how I ran hashcat: hashcat64.exe -m 2500 -a 1 --session blaha X:\blaha.hccapx X:\wordlist.txt X:\wordlist.txt
