Looking back, it looks like your TPE number was off a bit. You were at 288 TPE after the 2/11 update, then at 309 TPE after adding 21 TPE in the 3/2 update, so you actually should have been at 335 TPE after adding 26 TPE in the 3/10 update. Now you are at 381 TPE after adding 46 TPE in this week's update. The banked TPE numbers were already correct so you had 132 TPE available after the 46 you added in this update. Increasing Strength from 58 to 61 only costs 6 TPE, so I bumped it up to 62 since you needed to spend at least 8 TPE on Strength from your equipment. So you spent 124 TPE total with your upgrades, so you are left with 8 TPE banked.
