[githubgilhad]

Which expansion is problematic?
Cargo-Contract-Mod v. 1.5
( https://wiki.alioth.net/images/f/f3/Oolite.oxp.Switeck.Cargo-Contract-Mod_1.5.oxz
https://ooliteproject.github.io/oolite-expansion-catalog/expansions/oolite.oxp.Switeck.Cargo-Contract-Mod.html )

Describe the problem
from oolite 1.81 is Cargo-Contract-Mod v. 1.5 obsolete

• uses structures, which no longer exists - commodity.marketBasePrice, commodity.marketMaskPrice, commodity.marketEcoAdjustPrice
• so this._priceForCommodity(...) returns 0 everytime (oolite-contracts-cargo.js: 878)
• so all prices are 0, profit is 0, no contract can be profitable
• so no contract added to main station

This problem was addressed by its author in version 1.6 and 1.64
see https://bb.oolite.space/viewtopic.php?t=13757

Actual version is 1.64

Cargo Contracts Mod v1.64 -- works with Oolite v1.83 and later!
