I followed this thread the last days and can confirm some strange behaviour.

I) Also, my coin daemon very often outputs:

2017-Sep-14 11:57:31.476950 WARNING Block e9cbdae25c8078ff32d50ae0240f4e5bb31198ee8e499052c4c3a1a8339ea365 added to alternative chain. Index: 83162
2017-Sep-14 11:57:51.270018 INFO    Switching to alternative chain! New top block hash: e9cbdae25c8078ff32d50ae0240f4e5bb31198ee8e499052c4c3a1a8339ea365, index: 83162, previous top block hash: 5d0c5b01739ab78dafc9f78bf5ec2e8e16a1c134902f40985f72ecbc2360f506, index: 83161

II) My pool produces some valid blocks, i.e. block hash for height 83154 is correct one as listed on https://explore.leviarcoin.org/

III) Some blocks seem to be orphaned really, i.e. hash for height 83161 is different from official block list (see also above)

IV) Biggest problem: I don't know why my pool cannot unlock the valid blocks. Even if height 83154 seem to be valid it's marked as orphaned by pool.

I planned to setup a public pool and I have ~10% of total hash rate available at the moment. May be it's related to combination of low hashpower with really short block time. But I have no idea where to look further.
Any hints or ready to switch some hash power to my pool for testing purposes?

EDIT: @Invis your payment rate of 30-40% seem to be related to your pool hash rate only. Even if my pool cannot unlock block at the moment (I don't know why), my pool wallet receives full reward. So I assume, if your pool hash rate is going to be fixed then miner rewards will be correct.
