OR Object Texture Issues

[oper190]

Okay can someone explain these, note I am running OR 1.4
First why does OR use snow textures on objects that are coded 257 for night textures and day textures only? Not the worst case but...why???

Now my real issue: Testing my Route that I'm work on, I decided to do a test run in Winter clear.
Two of my own buildings have textures not showing in daytime Winter.

All buildings with arrows are my own designs all are coded 257: Summer clear run:

Winter Day: Red arrows textures not showing

Winter night:

Also there aer no errors reported in the OR log, it's clean.

Anyone one have any idea why these textures aren't showing in Winter day, clear or snow. Thanks in advance.

Just checked the Textures used, as they were used in other buildings.
The Dunkwit and Fire Department signs use the same texture:
Summer / Winter

The FD sign shows in both but not Dunkwit?

These four buildings use the same texture:
Summer /Winter:

Only the one doesn't show in Winter.

Now it's getting weird.
Same route running the test run in Winter Clear weather:
How did this happen?
Tunnel texture used in the Route's Texture folder as run in Summer:

Tunnels as appear in Winter:

Where did OR get this from? This texture is NOT in the Route's Texture folder, nor in the Global Texture Folder. It is used in other Routes.

New and "better" ain't always better. Never had these problems with MSTS.

Seems like I figured out the first problem with the buildings. Ran the same test in MSTS and had the same results along with other missing texture errors. From what I can figure, those buildings were built with a mix of textures, some with Snow textures and some textures that don't have them. In Winter, regardless of the texture code, 257 for night and day only, both programs want to draw Snow textures in Winter if they are available, and objects have to have all "snow" textures or no "snow" textures for them to be drawn correctly. With the mix they both freak out trying to mix snow textures with no snow ones at the same time in an object. Have to copy my regular textures into the snow folder.

As for the tunnel textures, any thoughts why it changes, especially when the texture used is NOT in the Route or Global Texture folders?

So I ranted - and apologize to anyone that might have taken offense.

Issue was totally my own. The textures in question had been modified but not updated in the Snow Folder, including the Tunnel Wall texture. Got brain lock and didn't look into it far enough on my end. All textures now up to date so hopefully no more issues, and now I know what to look for.
