problem with the new hqm skin

if i try and upgrade anything on the base to default hqm from the ui it turns into twig . but if i do it with the hammer it works fine . then if i try and change the skin for the hqm to the new one foundations look like they turn into floors and then the base will start to decay even if there is enough stuff in the toolcupboard 

Do you have any other build tools plugin or any other plugin that might be interfering with the upgrade
