Here is How and Why?
The reason you are having this problem is because your PC is set to not accept cookie (or you are browsing from another PC) this means that you are not known or recognized as who you are.
How it happens
You see a post you wish to reply, you 'press follow' AND at this point you are asked to log in! When you do log in this way, then the 'follow page" comes up, you complete it, AND IT IS BUG, your post is seen as a new head post!
Solution!
We are working on the source codes to fix this problem.
A. Log in as soon as you enter the TTT forum (from the menu)
B. Try setting your PC to accept cookie! This will help and sort the problem!
Again, thank you all for your patience.
