Reentrancy in LEGO.constructor() (#302-314):
External calls:
- _pair = IPancakeFactory(router.factory()).createPair(address(this),router.WETH()) (#307-310)
State variables written after the call(s):
- isExcludedFromFee[owner()] = true (#311)
- isExcludedFromFee[marketAddress] = true (#312)
- isExcludedFromFee[address(this)] = true (#313)
Apply the check-effects-interactions pattern.

LEGO._transfer(address,address,uint256) (#422-473) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > startTime,Not yet open) (#431)
- block.timestamp < limitTime (#433)
Avoid relying on block.timestamp.
