Patreon does not allow price changes for active tiers
Deleting a tier (old $5 Supporter, $10 EVE Collector) loses the rights of each tier. Repayment will be the same, but a tier with no rights.
To prevent this situation,
If you are in the $5 tier and $10 tier this month, please cancel the current tier repayment and sign up for the $8 tier next month (new EVE Collector).
Even if you cancel your current tier, your tier privileges will remain until this month.
