Hi Reishi. Sorry for the confusion and frustration. Looks like 'reishi' was generated after the fork, so only exists on hive, not on steem.
Splinterlands may at some point move to hive, but its still on steem at the moment.
Do you have discord?
The tech support channel would be the best place to ask. https://discord.gg/zpMKgVv
Include your usernames on both chains; the guys there will be best placed to advise further.
