Vessel recovery funds incorrecr with modded tanks
Some mods such as configurable containers, firespitter, interstellarfuelswitch etc. allow stock and non-stock tanks to hold non-default (selectable) resources.
When setting in VAB a tank (eg stock rockomax x32) to hold such a resource, eg an expensive one such as rare metals, the vessel cost/mass are calculated correctly.
Emptying the tank in vab recalcs vessel cost correctly.
Launching and immediately recovering the craft leads to recobery funds being calced INCORRECTLY:
the base cost seems to be the tank with full resources, since the tank is empty on recovery the actual recovery funds are negative (so loosing money for recovering the vessel).
Can be reproduced with only stock tanks and stock resources (eg monoprop), but needs a fuel switching mod, such as configurable containers, fieespitter, ifs or wildblueindistries.
