I might be a bug, but if you do the same TF within a 24 hour period you will indeed get half the rewards.
Did you do a synapse the day before?
If not i would recommend sending in a bug report on the issue.
There is a known bug where some players are recieving the TF reward twice (but the second award is half, because you have just completed the same TF).
Are you sure Synapse didn't award you 45 merits, then award you 22 merits?
I really should do something about this signature.
The Synapse problem has been posted about before (here? US?). Doing it within 24 hours of Posi gives some people a diminishing return. It's not meant to mind, so it is a bug....I'd petition for your extra 23 merits that you are owed.
Think I'll petition it when I get the chance to log on then.
And yes, I'm sure I hadn't done Synapse within the 24 hours because I only did the TF to get the badge which I was missing. Also I am sure I did get 22 merits, checked 115 before TF completion and 137 after it. 137 - 115 = 22.
Also some people in my team who I did Posi with an hour before the Synapse got 22 merits only.

Still missing my damn 23 merits as far as my maths work. Bleh. Should probably petition it again

I was just wondering if doing two TFs consecutively had an effect on the merits awarded from the latter. Yesterday I did Posi and Synapse in a row (phew, dont have to do them again in a while
) but only got 22 merits from Synapse while I did get the full 55 from Posi (which I did first).
What I understood from the message popping up after a TF is that doing two different TFs in a row shouldn't affect the merit rewards at all. So the question is, should I have got 45 merits from Synapse instead of 22?
