Describe the bug

Metal sheet stacks can appear with a 0 sheet count. This appears to happen most often as a result of explosions though i have no idea what may be causing it. these broken stacks can't be combined with other ones

What did you expect?

Sheets should always have a count above 0, otherwise they shouldn't exist
