Great initiative! I hope I will not update Senseless too often, because each time you need to fiddle with its code... :)

I'm already good in syncing folder contents with Total Commander and using Notepad++ ;)

I have had towns demand coal until 1920, and then fuel. Personally I did not find it an addition to the gameplay fun, so I did not include it in the final version of Senseless. Is that something you are after, or are "Briquets" the thing you are really after?

In the commented-out code, if you replace FUEL by your BRIQUETS, normally it should work. I test-played it with FUEL without crash, and no FUEL appeared in 1850. Maybe you have a mod that makes house from era2 appear in 1850? Or maybe you replaced the COAL by BRIQUETS?

Any way, the game should not crash, except when you use BRIQUETS cargo without them being loaded in the list of available cargo items.

And now I'm writing this, I might have a solution how to modernize CARS during the ages without changing the production chain.... but that is another subject that does not concern you and the BRIQUETS.

That should work, but you need to have a "brikett.cargo.lua" in the config/cargo_types folder with "BRIKETT" as a cargo type. Otherwise you have a crash.

In sandbox mode, set the date beyond 1920, and set the game in fast forward. It does take a few seconds to see the first houses changing.

I see. You can set the town size in the town editor at minimum (50), and see houses disappear on fast speed. Then you set it higher again (200) and the new houses should not have BRIKETTS.

I think personally it would be great too have some industries like briketts that should becoma obsolate at a certain moment. On that way you also get some lines and stations you must remove over time. It would also make the early years more interesting.

I agree, and I had planned to have such more dynamic industrial evolution, but I have not yet found out how to create popup messages to announce events. Without this information disappearing production/cargo/demand or goods are frustrating. That is why I did not impelement disppearing things.

The problem is the logic. All era1 houses have the "yearTo" field set to 1920. You need to test the yearTo>1920, and not yearTo>=1920. ;)

Yeah... sorry about the numerous updates, but crashes need to be addressed and fixed as quickly as possible.

Bulk Upgrader is a very useful mod during development or for fixing specific issues, but it has one important problem. It makes you owner of ALL constructions you upgrade. Maintenance costs will get you soon afterwards.

Do you have some spreadsheet or list of changes you made to industries? Very interesting.

The only way to tackle the problem without using OR is using intermediate cargo types. An exaemple:

A OR B = C

then

A -> X
B -> X
X -> C

A can be an AND-combination of several cargo types, and also B. they both produce a same intermediate product X, which is finally converted into product C.

This is a very ugly solution, but it completely eliminates the need of the OR logic. But I never did this, because is ugly, and not fun.

I've again send an email to Urban about the OR-function. We'll see, but I do not have much hope.
