'''Editorial note:''' This is a later ge-next cargo-capacity report, not the original discovery of classic GE's overflow. The screenshot and quoted chat show how an inadequacy in the early ge-next cargo fix was noticed. The [[Classic bug: Cargo weight overflow|bug article]] distinguishes the classic defect from the subsequent fixes.

== June 17: Planetary Transport capacity report ==

[Oliver shared game output from a Planetary Transport. A planet scan showed 217,993 food cases. <code>TRAN UP 217993 FOO</code> was refused with “There is not enough space available for that many items.” The inventory report showed 22,655,938 men, 1,902,680 food cases, other cargo, and a reported total cargo weight of 26,905,885 tons. The output also contained an unrelated “There is no such planet in this sector” message.]

; 4:19 PM — Oliver
: Bug on PT capacity?

; 4:39 PM — manicpoporg
: the weight calculation is overflowing the 32-bit long

; 4:49 PM — Oliver
: Why did that change?

; 5:21 PM — manicpoporg
: i don't know, the weight calculation has gotten too convoluted
: i need to rewrite it and probably have different routines for the 16-bit and 32-bit builds

== What this established ==

The refusal and unusually large inventory exposed a cargo-calculation problem in ge-next after its initial classic-overflow fix. The chat's “32-bit long” diagnosis was an immediate working explanation, not a complete analysis of every arithmetic path. Subsequent review led to architecture-specific cargo implementations in ge-next 0.3.1; the bug article explains those fixes. This screenshot alone does not show that the displayed Planetary Transport inventory was produced by the original classic exploit.
