Hello!
I am the author of Schall Pickup Tower.
And I am glad that someone make use of my mod(s) and make custom changes to that.
There is one thing I need to notify you though.
In the new version 0.18.2 released today, I have implemented part of your changes (not fully) to the PT I. So you may have to modify your code about the recipe and tech ingredients, and perhaps also tech prerequisite.
Thanks for your support.
Regards,
Schall
