When using dynamite, one cannot see and estimate the explosion radius. This should either be displayed or described in the description.
Also, picked up sticks of dynamite are no longer considered solid propellant and accordingly cannot be stacked or otherwise used, although the appearance or description does not change.
That should be corrected. Either by treating them further as solid propellants when they are picked up or by converting them to dynamite in the printer or the workbench with your own description and illustration.
