v1.55 hangs when opening planet

Hello,

I'm playing Supernova v1.55 and the game hangs completely (need to kill it via task-manager) as soon as I do try to open a certain planet. All other actions work perfectly. The biggest issue is that I cannot end the current month as the game suggests to manage that planet...

Is there any workaround or any way I can help you guys debug the issue?
