Ancient city structures are inconsistently named

The Bug:

Ancient city structures are inconsistently named.

Throughout the game, the names of some ancient city structures contain an underscore followed by a number at the end of them, and some of them don't, therefore introducing an inconsistency. Even when there's only one type of structure, "_1" should be present at the end of the structure's name. For example, the structure "sauna_1" correctly utilizes this concept and other structures such as "small_statue" don't.

Below is a table I've constructed that shows all of the naming inconsistencies within ancient city structures.

Affected Names:

Before reading the table, please note the following:

• Words colored in GREEN are correct.
• Words colored in RED are incorrect.

 

Steps to Reproduce:

• Locate any of the structure names listed above and compare them with other structure names.
• Take note as to whether or not ancient city structures are inconsistently named.

Observed Behavior:

Ancient city structures are inconsistently named.

Expected Behavior:

All ancient city structure names would contain an underscore followed by a number at the end of them to maintain consistency with one another.
