The Bioship Landing Platform effect does not properly multiply with cloak buffs unless it it is built
before cloak buffing structures are placed on the planet. This is not a world-ending problem, but given the importance of planetary cloak, it should be fixed so that it buffs regardless of where it is placed on a planet. It's a bit counter-intuitive to be forced to place your Biosphere Landing Platform on a planet
first to work around this issue, since strategic players will naturally wait for the planet to be colossal (or better) in size before deploying -- most likely long after a % buff arti is already on place on that planet.

For example, if you build an Ergosphere Filter, then add a Platform a few minutes later, you will get something like this:

Here, the planet had 8050 standard cloak multiplied 1.2 times by the Ergosphere Filter, with 250
added by the Landing Platform; because the Platform was built after the Filter, its additive bonus was not multiplied.
Ah, but if you place a cloak buffing artifact on the planet
after the Platform is deployed, it plays just fine with that structure:

Here, the planet had 8250 standard cloak, with 100 added temporarily via Void Shell, multiplied by 1.2, with 250 added by Landing Platform, and multiplied again 1.15 times by Polaron Emitter (build on the planet after the Landing Pad), for a total of 11810.5.
Why is the Void Shell important? Because by making sure it is added it to the top of the list, it gets multiplied properly, which is how the problem with the Landing Platform could be solved.

Did a ton of experimenting with this last night, and it is not an isolated incident or limited to certain types of buff artifacts.
Here is a planet with a Litheor Core tunnel multiplying cloak, while the Landing Platform (added later) only adds its cloak:

2750 standard * 1.23 buff + 250 effect = 3632.5
And here is a planet with a ton of cloak buff artis working in perfect harmony, because the Landing Platform (added first) is properly multiplied:

5600 standard + 250 effect * 1.3 buff * 1.20 buff * 1.25 buff = 11407.5 (huh?*)
Many Mylarai Extractors died to bring you this information.

*er... so why did it round down the .5 here while it rounded up in the other two? I don't know, but that's probably for another thread
