Forum Solo ads Broken Click Tracking?

Are any other solo sellers noticing that their clicks are not accurate? For example I use my own click tracking service and with Safeswaps my click tracking and Safeswaps were pretty much right on. With a campaign I'm running today my click tracking is saying 260 raw clicks and Udimi stats are saying 180 raw clicks. That is a big difference and it appears to me like the Udimi tracking is broken. So I'm looking to see if any other sellers that do their own tracking are noticing click discrepancies.
