Scenario Modding - Mod File Size Workaround

[tmas]

I would like to create a scenario of rebuilding a megabase that got destroyed by a big explosion. Unfortunately, the file size went from 53MB to ~530MB after the destruction. The mod size limit is 263MB. Is there a way to split the scenario containing the save into two parts to work around the mod size limitation?

To be exact, the explosion was caused by a Hiroshima grade artillery shell from the mod True Nukes. If there's a way to compress the save file size to under 263MB, that'll work as well.
