The calcLpTokenSupply function may not always converge within the 255 iterations limit. If it doesnt converge, the function will silently exit the loop without returning a value or throwing an error. 
Take a look at the calcLpTokenSupply function: https://github.com/code-423n4/2024-07-basin/blob/7d5aacbb144d0ba0bc358dfde6e0cc913d25310e/src/functions/Stable2.sol#L74-L103
The issue here is that if the loop completes without finding a convergent solution, the function will exit without returning a value, leading to silent failures.
Consider adding a revert statement after the loop to ensure that if the calculation doesnt converge within 255 iterations; the function will revert with a clear error message. Here is the recommended change in diff format:
