SC1000 bombs on German aircraft bug?

[=KG76=flyus747]

Flew a 111 tonight, dropped 2x1000kg bombs within split second of one another.

 

The explosions however, was one of a 500kg bomb and the other was a normal 1000kg explosion.  

 

Is there some sort of memory limitation in IL2 where two 1000kg explosions cannot be displayed? Or was the first bomb really only a 500kg bomb?

 

After watching replay, I know I had 2x1000 kg bombs no doubt.

1. The 2x1000kg bombs
2. Left explosion is first, bombs fell within 1 second of each other
3. Aftermath (I know they weren't the best drops but a lot of the buildings intact for some reason)

 

Anyone else experience this before?

No I can't say I've experienced this although it's rare that I take the two SC1000 loadout. I'll have to try it out.

I cant replicate this with consistency but this has happened to me on several occasions especially when I drop the 2x1000 within a split second of one another
