You would need to adjust your ticket fee to get your tickets mined into a block. POW miners pick tickets with high fee to low fee first. You can view the trend of Avg ticket fee in https://dcrstats.com/ and adjust your ticket fee accordingly.
I know the team is working on fixing the ticket algorithm in next release. So we will have more stable ticket prices. This issue likely gets resolved. BTW I am not a developer. I am a hodler like you.
Join slack and ask questions to the developers. They are very responsive.
