In my topic is a lot of post (almost 300 on about 8 pages). I created a new post in the end of topic and changed its date to move it up as second post of topic. It's working, but there are also small issues with it.
- Issue with edited post
Now when I edit the mentioned post and save changes I end on last page of topic and not on the post as expected. It's not big issue, but it's kind of annoying, because I have to search for the edited post to check it. - Issue with last post
phpBB think that newly created post with changed date is the latest post of topic.
For example I have last post „A“ in topic from 01 June 2018 and create a new post „B“ after this post. Than I change a date for post „B“ to 01 March 2010. Post „B“ is moved to the front of topic, and post „A“ is last once again. But phpBB think the post „B“ is last (even if it's in the front of a topic now and there are a posts with newest date) and it means that it is lost between topics from year 2010 on viewforum page.
