Just some notes on using contract packs with GPP.
CommNetRelays, ExplorationPlus, Bases and Stations worked out-of-box (for GPP 1.2.2)
Tourism Plus works. But some waypoints look weird with their names... (Badlands, etc.)
Clever Sats kills your exploration contracts. A quick workaround is deleting GPP's GameData/GPP/Gael/Agencies/Agents.cfg . See this comment:
Field Research only partially work (some contracts like performing experiments around KSC never appear). Replacing every occurrence of (word boundary)Sun(word boundary) with Ciro and every occurrence of (word boundary)Eve(word boundary) with Niven within that contract pack seems to fix it. (though the Niven part sounds a bit inaccurate...)
Bonus notes on rescaled system (Currently trying out 2.5x):
Tourism Plus suborbital waypoints are about 15~20km below atmosphere boundary, which makes them impossible to complete. Possible workaround:
Do not attempt to rescue kerbals stranded in low Gael orbit (stock contracts).... lol
