• The game now checks that technology levels are contiguous.
• Non-upgrade technologies are now considered to be level 1; previously they were level 0.

• "energy-shield-equipment" logically followed by "energy-shield-mk2-equipment". "energy-shield-mk2-equipment" should be "energy-shield-equipment-2". This causes problems with mods that number their internal technologies in logical order ("energy-shield-equipment-3" would cause 20.916 Error ModManager.cpp:1294: Technology battery-equipment: Non-contiguous levels: 1, followed by 3). And yes, addressing as suggested will break the mods that updated to adjust for 0.17.23 change.
• "battery-equipment" logically followed by "battery-mk2-equipment". "battery-mk2-equipment" should be "battery-equipment-2" with the same explanation as above.

First of why is this suddenly a critical problem? The game worked just fine before and suddenly you break a ton of mods. Why make this a fatal error without any advanced warning? You could just make the game output a warning when this happens, even with a popup on load. But why not give the user the option to ignore this so they can still play? Give modders a chance to clean up their prototypes instead of breaking the game for most users.


Secondly the check is stupid. As in: It fails when it should detect a continuation of technologies.

For example boblogistics has

Code: Select all

  {
    type = "technology",
    name = "bob-logistics-4",
    icon = "__base__/graphics/technology/logistics.png",
    icon_size = 128,
    prerequisites = {
      "logistics-3",
      "advanced-electronics-2"
    },

For the user this clearly is a continuation from logistics-1, logistics-2, logistics-3. The name is chosen so it will not conflict with other mods, which is a good style.

BUT: 19.093 Error ModManager.cpp:1294: Technology bob-logistics: Non-contiguous levels: 0, followed by 4

Because "bob-logistics-" != "logistics-" this fails your check.

This new check forces every mod that extends belts now to have a technology "logistics-4" causing them to break each other. Or they have to use something like "bob-logistics-4-this-check-is-stupid" and break that the tech is an upgrade of "logistics-3".

PLEASE reconsider this issue.

If you want to keep checking the continuity of technologies then use a naming convention that allows for mods to have non conflicting names. An alternative would be to make the technology progression more explicit, like entities have a "next_upgrade". Technologies could have a field "upgrade_for" and you check that the level of the tech is one larger than the level for "upgrade_for".
