Sorry it took so long to get this. I'm not entirely sure why I set the default range to 20 for all of the spider-weapons (excluding the spider-shotgun, which was set to 15), maybe for some kind of balancing reason?
Anyways, I've changed it so that the original weapon range is copied during the initial data step, and then re-copied during data-final-fixes, in case the original weapon range was modified (so it should theoretically always match the base weapon range, unless other mods change it during final-fixes, after this mod runs)
I'm not entirely sure how useful a Railgun/Tesla spidertron would be, especially with the new ranges, since if both weapons have ammo, but one weapon can't fire due to range, then it will never switch back to the longer ranged weapon. Maybe that's why I had all the ranges set to 20.
Ah well, short range railgun wasn't all that useful to begin with, so it probably wasn't worth mix-and-matching with other weapon types anyways. Nice buff to dedicated spidertron variants though. Implemented in v2.0.10 (and retroactively applies to the whole squad as well!)
