Hey,
I will release the updates for Strange and Fire UI tomorrow evening...
Until then, you can delete the following file/folder in order to temporarily fix the issue:
\Data\Gui\Customized\Views\MainGUI\MainSplitView.x ml
\Data\Gui\Customized\Views\FeatGUI (the whole folder)
This might not look awesome, but it will allow you to use the multi feat system
Thanks for your patience !!!!!
ps: if you feel adventurous, you can try to apply a fix by following the steps described by MashMash here:
