A quorum of Senators (5) have voted on this amendment. With 4 Ayes, 1 Nay and 0 Abstentions, this amendment has passed
We should ever even be in this kind of situation struggling with a quorum, 5 senators of 9 voting, frankly, isn't good enough

I'm not a senator, but how is 4 out of 9 in favor enough to pass an amendment?
For an amendment to an amendment it is. There were 5 votes total, which out of 9 is a quorum and then 4 of the 5 votes were in favor. Altho, if BRTD hadn't cast his Nay vote, we'd have had only 4 votes and thus no quorum.
I see Jas has voted, making this irrelevant, but your assertion that 4 out of five votes makes a majority seems erroneous. The Senate rules clearly call for a majority of office holding Senators. Five gets the quorum, but the vote must still be out of nine Senators:
1. Once a senator calls for a vote on the Amendment(s) under consideration, per Clause 2 of Section 3 of this article, or once debate time expires, per clauses 3 and 4 of Section 3 of this article, the PPT shall open a vote on said Amendment(s). This vote shall last for a maximum of five (5) days during which time the Senators must vote. Voting may be declared final at any time if a majority of office-holding Senators has approved or rejected said Amendment(s). Any and all Senators who do not vote will be considered to have abstained. A majority of office-holding Senators had not approved; four approved, one rejected, and four abstained. You got a quorum but not a majority approving.
I see the amendment has passed now, but I'd like clarification on the rule that states four out of nine is a majority.
