webapp messages are duplicated from one topic to another

[winza]

How do I reproduce this
I go into different topics that are many years old and have many messages
I start scrolling to the very top to the first message, go to another topic and repeat the same thing
I do this several times, each time in different topics
And then duplicates of some of the last messages appear, they always start to be transferred to each topic, even where there was one message in the topic before, many messages from another topic are immediately added there

In addition to this, there is also desynchronization between webapp and tindroid Somewhere you delete a message completely, it is deleted, but in another click it is not Or sometimes you delete a message, it seems to have been deleted You update the web page, it remains
