Critical Bug - troops are slowing down not progressing

Having a problem where the entire troop except hero gets completely slows down during the battle. It used to happen before occasionally but now almost every second battle this happens. Attaching the video. Don’t know whether it’s to do with the combination of orthodox towers in defense and having bia power. It completly screws up sine had to loose more lives and gems for simple battles


Could you upload the video for example on youtube or dropbox so we can have a look?


Do you use trebuchet? I noticed mine were stuck and they blocked the path, preventing reinforcements from arriving.
