Yes, sorry, was a late night last night.
Examples:
. 8 msg-id sub
. 9 msg-param-months 1
. 10 msg-param-sub-plan-name Monthly\sSubscription\s(dansgaming)
. 11 msg-param-sub-plan Prime
. 8 msg-id sub
. 9 msg-param-months 0
. 10 msg-param-sub-plan-name Channel\sSubscription\s(LIRIK)
. 11 msg-param-sub-plan 1000
Both are new subs, one is prime, other is plan 1000. Prime shows msg-param-months 1 while the paid shows msg-param-months 0
Then second month of Prime is msg-param-months 2, same as second month of paid. Paid plans always scip msg-param-months 1
