Issue Description:

What happens:

Altar can have negative progress (example with -2), probably at most negative drain rate.

What you expected to happen:

0 progress if all LP is drained

Steps to reproduce:

1. Build a T2 altar
2. Produce a not divisible by 5 amount of LP in the altar by using displacement runes and destroying them before the buffer is filled
3. Try to craft an item with a high drainage rate that is not a divisor of the current amount of essence in the altar and with an amount needed to craft that exceeds the currently present essence in the altar
